Re: Sims 4 crashes after loading; tried every fix I can find
@DoctorSyzygy Your new dxdiag doesn't list any new errors from Game Bar: the errors you're seeing were the same ones as in the first dxdiag. It's sometimes difficult to be sure without timestamps, but in this case, you can be reasonably sure by comparing the two lists and noticing that the new dxdiag has three new errors plus the first seven from the previous dxdiag, in the same order.
As a side note, it's not typically necessary to uninstall Game Bar—disabling it should be sufficient—and Microsoft may reinstall it the next time it updates. So please make sure it's gone from Settings, and if it's back, just disable it again. It's definitely not worth messing around in the registry just to get rid of Game Bar.
Speaking of the new errors in the new dxdiag, you have three BlueScreens, as you can see. Did these happen while you were playing Sims 4? If so, I'd like to see the crash dumps. Open a File Explorer window and enter C:\Windows\Minidump in the address bar. For the last two or three dump files, right-click and select Copy, then right-click on the desktop and select Paste. From there, you can zip the files together, upload the .zip to a third-party filehosting site, and link it here.
If there are any recent Sims 4-related crash dumps, I'd like to see one or two of those as well. Click Windows key-R and copy and paste this:
%LocalAppData%\CrashDumps
If you see any Sims 4 dump files from the last couple of days, please upload one or two as well.
