If it's a Windows build, then nothing comes to mind other than somehow the files got corrupted. Please redownload the game and try again. If it doesn't help, we could send a build with debugging enabled to see if it tells us what the issue is.
Dont worry it somehow got fixed i was in the early start and started a new save and skiped until that part which crashed after that i played normaly and saved and could load normaly. But i would check it if you have time i already send the screenshot so yeah. But now it goes well and this game in interesting thank you for your time!
