Hi y'all, 

Everytime i load up my game, it freezes then crashes. I have tried the spilt and check menthod and sometimes it crashes and sometimes it doesn't but it doesn't seem to be a specific mod causing the issue, it just crashes sooner with more mods and cc. please please help i've been trying everything for over two weeks. i've repaired the game, uninstalled and reinstalled. my only two options left are to delete and redownload all mods and cc which numbers in the thousuands so that would take weeks, or starting a new save which would take atleast a week inbetwwen building and cas. i get a crash report but i can't make sense of it. please i'm open to any suggestions at this point. :) 

sincerly, a very frustrated and discouraged simmer

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 when you test with no mods/cc ?

  • Delete the ones you have
  • Trigger the error again
  • Check if new ones are created
  • If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Posting the info is meant for troubleshooting.

      Hi KSMJ13​ 

      you can't attach the file. You need to either upload it to a third party site or copy/paste the content.
