Stellaris Dev Tracker

Avast is the AV app causing us the most problems at present. You might need to get help from their support to ensure that the launcher and game can read and write to the Windows User Documents folder.

You may not have mods_registry.json as that's an old file no longer used, but the sqlite one ought to be there. In Windows Explorer click on Documents in the left column, then in the right pane double click on Paradox Interactive and Stellaris. You should see it in there. Depending on your Windows Explorer settings it may display as just launcher-v2. And the mod folder should be there too.  

I think you have at least two separate problems, with the launcher and the game/Windows.


For the launcher, despite what you've tried it is almost certainly an antivirus problem. Please try the following:

- unsubscribe from all mods
- delete the folder Documents/paradox/stellaris/mod/
- delete the file Documents/paradox/stellaris/mods_registry.json
- delete the file Documents/paradox/stellaris/launcher-v2.sqlite

Add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list. You should add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.1/paradox launcher.exe to that list.

- subscribe to a few mods
- run the game up and see if those mods are now available to you.


For the game, DXDIAG is a program you run from a command prompt or the Windows start me... Read more

That crashes on my iMac but not my Windows machine. So I guess it may be an issue with Big Sur.

If you can get access to any Windows machine just run the game past that date, then you can probably move back to the Mac.

As for the bug can you make a new thread in Bug Reports forum here please, attach that save and make it clear the crash happens on MacOS only.

Sorry for that probem!  

Illegal instruction means there is a command in an executable that is not valid for the CPU to interpret. That's a pretty unlikely bug to get through any development process!

It tells us nothing about where the problem is or how to avoid it.

If you have a save game file that reliably shows this problem, please attach it here, preferably from just before the crash happens. I can test it on my iMac and Windows machines.  

Does this only happen on speed 5? What do you see on lower speeds?

May as well update that nVidia driver to the 2021 one:
Download Drivers | NVIDIA
And set the refreshRate in the launcher to 60.

If none of that helps, is fullScreen mode any better?  

Removing openGl should have helped to some degree, as that is slower that DirectX. Are you saying removing that made no difference at all?

Can i see new copies of all five of those files I asked for before, please?  

highscore07 said: Termination Signal: Illegal instruction: 4

That's a pretty serious bug, if it's a bug. Are there any mods involved here?

Can you try that save on a Windows machine?  

I don't know what might have changed a few days ago as there's been no game patch recently. I guess it might be something at the back end.

I'll run it by the devs, but it may be an IT issue.  

FYI the only supported distro is Ubuntu.


Has this game always been like this on this machine? Or it used to work?

Our similar game Crusader Kings 2 is now feee to play on Steam, does it have the same problem?


Please attach your Documents/Paradox/Stellaris/settings.txt and pdx_settings.txt .
From your Documents/Paradox/Stellaris/logs/ folder, attach system.log , error.log .

Also in Steam please click on Steam-Help-System Info, and paste everything there into a text file and attach that here.  

If you move user_empire_designs.txt from /Documents/Paradox Interactive/Stellaris/ , does the game then start?  

His launcher is old and has failed to update itself.

Please try this:

- exit the Steam app entirely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still present:

- C:/users//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//AppData/Roaming/Paradox Interactive/launcher-v2/
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

- run steam.exe as the Windows Admin user

- run the game from the PLAY button in Steam  

Xalya said: The only way i get it to work, is to disable my Avast Antivirus.
as long as my Antivirus is running, no mods.

As above, if you except the game and launcher .exe files it should work. You may need to contact Avast support to get that set up right.  

Does anyone playing the game use the MP 'helper' utility GameFirst? If so they need to unload it before playing our games.  

EcrofLeinad said: Yeah, this is the same thing that happened in January. They released an in development launcher (version 2020.17). They "fixed" the issue by re-releasing 2020.16 (although the folder/files downloaded said 2020.17.1). 2021.1 appears to be the same exact launcher as 2020.17 with all of the same Steam Workshop Mod related issues. Read all about the 2020.17 release here: ...

Hamakaze said: Yeah, that didn't work. It's thoroughly borked for me.

Add C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.1/paradox launcher.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.


If that doesn't work let's try a clean reinstall of the launcher too.

- exit the Steam app entirely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still... Read more

I see Steam mods in my installation, interesting. I guess go through this please!


- unsubscribe from all mods
- delete the folder Documents/paradox/Stellaris/mod/
- delete the file Documents/paradox/Stellaris/mods_registry.json
- delete the file Documents/paradox/Stellaris/launcher-v2.sqlite
- subscribe to a few mods
- run the game up and see if those mods are now available to you.  

I assume this is a side effect of the new launcher, although I saw no such issue myself. I guess a restart from scratch is called for:

- unsubscribe from all mods
- delete the folder Documents/paradox/Stellaris/mod/ (after moving your local mod files elsewhere of course!)
- delete the file Documents/paradox/Stellaris/mods_registry.json
- delete the file Documents/paradox/Stellaris/launcher-v2.sqlite
- subscribe to a few mods
- run the game up and see if those mods are now available to you.  

That version uses a different stellaris.exe which will need to be let through all firewalls separately to the standard one.  

In the game launcher please set Display mode to Borderless.

IF that doesn't help, Has the game ever run successfully on this computer? Or never?

IF IT USED TO RUN:
Please do a full **clean** re-install:

- move any valued save games elsewhere, and user_empire_designs.txt from /Documents/Paradox Interactive/Stellaris/ if you have made any custom empires or races.
- "uninstall" in Steam-Stellaris
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox/Stellaris folders
- re-install game in Steam, run a Steam Verify when done.
- add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular you need to make sure there are no files or folders left under either the Steam Stellaris or Documents Stellaris locations, be... Read more

Please unload GeForce Experience and test the game again - does it still have this problem?


And, why are you running the game in openGL mode? That is always slower than DirectX, please undo that.
