Re: Windows 11 and ts4?
@essiewik If you can play for 30 minutes, as in, Sims 4 loads and runs correctly for at least a little while, then the game is compatible with Windows 11. There are plenty of reasons it crashes that have nothing to do with the OS, including but not limited to bad custom content. (Even one bad cc item can cause a crash.) To provide more information, please run a dxdiag and attach it to a post.

Please also let me know whether you've noticed any pattern to the crashing, like for example if it always happens at a particular sim-time, or when your sims are on a certain lot, or when particular sims are present or wearing particular outfits.
