heres the full crash log thing if that could help
April 2021
@Gagie123 I asked a couple of knowledgeable people for their thoughts on this thread. One note is about the info listed in your crash log: it states that the library running Sims 3 found a serious error and crashed the program, but it doesn't say why. (This is typical of crash logs.) So figuring out the why still requires some experimentation.
Please list the install location of the Sims 3.app, as in, is it in Applications, Users > your username > Applications, or somewhere else? Please also go back to Security & Privacy > Privacy, where you found the Full Disk Access settings, and open the Files and Folders settings in the same location. Check all the boxes for both Origin and Sims 3, restart your computer, and test.
Also, please let me know whether Origin or Sims 3 is listed in the Accessibility settings in the same location. I'm not sure whether it matters, but it was mentioned in the conversation, so it's worth checking.

@Gagie123 Try unchecking the Full Disk Access boxes and then manually checking everything under Files and Folders. It's possible that the settings don't quite cover everything, even though they should.

Neither origin or sims 3 show up in files and folders after I unchecked full disk access

@Gagie123 Just checking, but did you click the lock to enable changes? If so, please restart your computer and look again, to be thorough.
Edit: It would also be helpful to see the window with the Files and Folders settings showing. Hover your cursor over the window, click cmd-shift-5, and it'll take a screenshot of the entire window.
