Europa Universalis IV not working (EGS)

I'm trying to play EU4 through Epic, after Paradox launcher the game just stays stuck on the startup splash screen.

If I launch eu4.exe directly via Steam, it gets to "processing flags" and crashes after that

So, after thorough testing it seems like when launching the game (launcher or directly the .exe) through heroic it's stuck on the startup splash screen. Launching either on Steam gets to "processing flags" and crashes after that.
I've tried these solutions I found on google and they did not work

set multi_sampling=0multi_sampling=0 in settings.txtsettings.txt
delete files related to loading flags

examine error.logerror.log, which contains only this:

[main.cpp:1345]: Failed to backup error log

[main.cpp:1345]: Failed to backup error log

I don't have any mods installed.

I was able to launch the game yesterday after installing but I did not try restarting the game
