Is there also a crash report, with a long ‘GUID’ string displayed, that you could paste in here please?

where should i find it?

It should pop-up right after the crash! :slight_smile:

there was no popup i can only dismiss the window i posted as a screenshot and steam shows me, that the game is no longer running.

I wonder if its an issue loading the user’s profile in windows. German Windows has C:\users in a very different directory structure. I’ve seen this be an issue in other games

i fixed my problem with a coplete reset of my system

When you say ‘complete reset’ do you mean you reinstalled windows ?

Yes reinstall of Windows
