Did you re-download the game ? - Just to make sure, you are not trying to run faulty/corrupted files ...
Did you try the quick-start ... skipping the intro ?
Then there is to look into your hardware and OS ... if your rig can barely handle the OS (forced upgrade Win7 ==> Win10/Win11) ... you will get into trouble with running any demanding software ...
There is a reason, I did not switch to Win10/11 ... my old lady doesn´t like them ...
