You tried HOI4 in both Steam and Nakama modes I guess?

But either way, I have no real explanation for what you are seeing there.  

But if you use Steam MP it is okay, are you saying?  

When using Steam MP, all traffic goes via the Steam servers - being on the same network doesn't change anything.

But from what you say this seems like an issue on that 5GHz wifi network rather than a game or Steam problem. Have you rebooted or reset that router?  

This may be a bug in the launcher, which seems to require MacOS 12 now. Were you at all thinking of updating MacOS? If so please do that and confirm for me that it helps, then I can report that to the developers.  

IF that doesn't help, in this folder are some .log files:
C:/users/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.  

Please try this:

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

Delete the following folders if still present:

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

- exit the Epic app entirely
- run EpicGamesLauncher.exe as the Windows Admin user
- run the game from the Epic client

IF that doesn't help, in this folder are some .log files:
C:/users/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.

Note that you can run eu4.exe directly from File Explorer, which bypasses the launcher.  

Please delete the ~/Library/Application Support/Paradox Interactive/ folder. To see it go to the Finder, hit command-shift-G (ie Go To) and paste in ~/Library/Application Support/ . Then run the game from the PLAY Button in Steam, to reinstall the launcher.

If that does not get the launcher running, we will need these files from that same folder:

Attach ALL .log files Found here ~/Library/Application Support/Paradox Interactive/launcher-v2/

The 1603/1605 errors we see there are typically a previous other installation stuck, or a problem in the Windows update/install processes.

If you see msiexec running in Task manager-processes, kill it and try this launcher install again please.

Otherwise run the Update app in Windows, does it load okay, find anything to apply - whether a patch, update? If so do that and reboot, then try this launcher install again please.

If still no good, do you see Paradox Launcher v2 in the Windows Control Panel to uninstall? If so does it uninstall cleanly, or get an error doing that? You can use this MS tool to clear the stuck install/uninstall:

Does your host also show that same version, 1.34.4 ac5e? If not the problem is on their end, they have a mod in use most likely.

If you both see that version, try having both of you select the Nakama MP game option from ythe mini-menu you see when you start the game from the Steam PLAY button (not a shortcut).  

Please try this:

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

Delete the following folders if still present:

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

- exit the Steam app entirely
- run steam.exe as the Windows Admin user
- run the game from the PLAY button in Steam
OR
- exit the Epic app entirely
- run EpicGamesLauncher.exe as the Windows Admin user
- run the game from the Epic client

IF that doesn't help, in this folder are some .log files:
C:/users/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.

I was referring to the dialog that comes up when you run the game from eu4.exe , saying some features may not work properly when the game runs that way (eg mods, sometimes DLCs). I'm sure that's WaD, yes, as no doubt they wrote it deliberately!

I wasn't aware of the two different Steam IDs thing, no.  

If it is a Steam glitch, as I think you are saying, then we won't be looking into it further.

FYI we don't have other such reports so it's very likely a Steam installation issue on your machine. A clean Steam reinstall (delete everything in the Steam folder except steam.exe and the /SteamApps/ folder) will probably fix it.

You could try over in User Mods (as they are experienced in editing save files), but in general uncorrupting any computer file is like unscrambling an egg!

What I suggest for the future is to make a manual copy of your Ironman save file just before or after each play session, just in case.  

If you load this save on any other machine you might have access to, do you get the same problem?

If so probably best to post that save in Bug Reports here, for QA to look into.  

Right click on eu4.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.
Then in the launcher Game Settings menu, select fullScreen display mode.

Then edit the file Documents/paradox/eu4/settings.txt to say:

Vsync=off, refreshRate=60.


Is that any better?  

I don't think so, as their family sharing feature requires to borrower to NOT own the base game, whereas the subscription requires base game ownership.  

In the game launcher please set Display mode to Borderless. THEN go here:

Latest supported Visual C++ Redistributable downloads

Not really, no. It would probably take a development-level tools to see that, if you have access to such things.

@grotaclas do you have any suggestions in this area?
