I see you are in the beta of the launcher, which is actually older than the non-beta at present. Please opt out of that beta.

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

No issues evident in those files I'm afraid.

You still get that same error as above? Does it show by itself as the launcher runs, or when you go in to look at mods, or when exactly?

Are your mods subscribed in the Steam Workshop or the Paradox mod site?

Either way, do the mod files physically exist here?
Documents/Paradox Interactive/Stellaris/mod/

Oh, so this only applies to uploading or creating mods, is that right? Because that's not how I read your OP here!

excosy said: The launcher always warnings this. Also I cannot create or update mod.

Sorry if I misread you.

I have no Create Mod button either, and I'm on Win10. Are you saying you do on Win 10?

On your Win10 machine is your launcher the beta one you show here, or the non-beta 2021.10?

Ah, I see now - that CREATE A MOD button does not come up until you ht UPLOAD MOD first. I've never looked into this area before! That works for me on Win10.

So we have two variables here - Win10 vs Win11, and launcher 2021.10 vs 2021.10-rc3 . Hard to say which is more likely the cause !

In Win11 make sure all these .exe files are allowed through the firewall:

stellaris.exe and dowser.exe (in the Steam Stellaris folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.10-rc3/paradox launcher.exe
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

If it is the same as the Windows Defender one in Win10 (I don't have Win11 yet to see) you need to allow then in both the Public and Private domains in that app.

excosy said: rc3 is beta version, does it mean Win10's newer than Win11's? has Win10's been updated?
2021.10-rc3 is actually older than 2021.10 . I don't know what functional difference there is, sorry.


As far as the server goes, Amazon is having a major outage:

Amazon Down? Service Status, Map, Problems History - Outage.Report

See if Amazon is down or it's just you. Check current status and outage map. Post yours and see other's reports and complaints outage.report
Nothing we can do until they fix that I'm afraid!
