A friend cant enter his condo

Hello there!
A friend of mine cant enter her condo since over a week now, she always gets instantly a fatal error she tried to turn off her workshopstuff and everything but it wont let her in

if anyone has an idea please respond

First of all, tell her to verify the game files by right clicking the game on steam, click properties, click the “local files” tab, then click “verify integrity of game files”. If that doesn’t work, then try sending a crash dump. If you don’t know how, then this thread should help.
