Re: How to identify the issue in Last Exception file?

After deleting or removing your mods and custom content did you clear your game cache and delete the and localthumbcache.package from the Sims 4 folder to help with troubleshooting?

If not, try that and then try the game again as a test, without any older saves or mods/cc installed to see if it plays okay.
