Game keeps crashing

@lauraaliceeeee  It's a really bad idea to disable Windows Defender's real-time protection unless you have a third-party antivirus running, or you're going to be very careful not to open any external sites while the feature is disabled.  Otherwise, your computer will be left without any protection at all, and it only takes one malicious pop-up to infect your system with a virus.

If the problem here is in fact Windows Defender, then the next step is to figure out why, for example disabling Controlled Folder Access or setting exceptions for Origin.exe and TS4_x64.exe.  You could also try playing while your computer is offline.
