Before performing any of the recommended troubleshooting steps listed below it’s best to restart your computer first. This action refreshes the operating system and removes any corrupt temporary data that could be causing the problem.

There are several factors that can cause this particular problem ranging from a corrupt game file to an issue with the graphics driver. Listed below are the recommended troubleshooting steps you need to do to fix this problem.

Delete crash report files from Sims 4 folder

The first thing that you should do in this case is to delete two files namely the lastCrash.txt and lastException.txt files. The lastexception.txt files are created when the gameplay code has an error.

  • Go to the C:\Users\YOU\Documents\Electronic Arts\The Sims 4 folder.
  • Find lastCrash.txt and lastException.txt files and delete them.
