I was playing on game pass and it told me my game files are unable to be accessed. Game played normally though.
Later on I got an error that i was unable to save any game at all due to corruption/no space left (see attachment). I deleted my "CK3" "My Documents" folder which resolved this issue previously. This did not fix the issue as it did before.
After this, the launcher does not load. I purchased the game on steam to see if it fixed this issue, which it does not.
The launcher just infinitely loads.
Edit 2:
I was able to completely remove all traces of the Paradox Launcher and all of the my documents folder, and then reinstall it in steam, verifying integrity.
The launcher still infinitely loops, in the xbox game pass store and on steam.
Edit 3:
I followed all instructions from this thread
steamcommunity.com
and it did not resolve the issue. Still looping in both stores.
If I try to start the launcher by itself, it says there was a general error (see attached). The launcher also continues to run in the background when I close it, and I have to use task manager to force close it.
