So, weirdly enough, yesterday after also deleting all my custom maps and my windows TEMP folder and restarting my PC, it worked again. Then today, I had the same issue as stated above.

@magge other games have no issue. I have an NVIDIA GeForce RTX 3080

@MostLostNoob This did the trick for now, thanks! So I should do this every time now I guess..

I have a few game logs here of my last 3 tries of playing:

game_21981172.log
game_21981157.log
game_21981052.log

Hi guys,
I've played hundreds of games without problems before some years ago, recently wanted to get in the game again and played a few matches. In my last game I was lagging unfortunately, so I tried to leave. However, when using the menu my PC froze so had to force quit the game with Task manager.

Now, when I try to start the game (both from the FAF client or from steam or directly using the *.exe file), the screen turns black, then minimizes and I get a minimized grey screen doing nothing. .

I've tried reinstalling the game from steam (new download) and reinstalling the FAF client as well.
I also removed the game.prefs file. All to no avail unfortunately.

Hope someone can help me with this!
I'm on Windows 11 Home, Intel(R) Core(TM) i7-10700K CPU 3.80GHz
