Fivereborn has stopped working

Hey guys i have some problems with a friends client, first he had an infinite loading screen, i fixed that , after that he had another thing , i fixed that too but now i can’t get over Fivereborn has stopped working and i don’t know where to try.
Can someone give me some tips?

Run as administrator? Clear cache?

game reinstalled, administrator not working either


How did you fix the infinite loading?

by reinstalling the game, corrupt download files
