Re: Sims won't launch on new PC
@vtori27 Nice computer. You certainly don't need the Legacy Edition, so put that aside for now, figuratively speaking. You don't need to use compatiblity mode either—the game runs fine in Windows 10, at least most of the time—so please undo any compatibility setting.
Your dxdiag doesn't list any errors that are obviously Sims 4-related, although the failed update of Windows gaming features may be worth addressing. For now, try simply turning off Game Mode and Game Bar, both of which are under Windows Settings > Gaming.
A component of Microsoft Office is also crashing, specifically a component that checks your currently installed features against what your account owns. I don't think issues with Office should interfere with Sims 4, although I guess anything's possible if they're fighting over the contents of Documents. It's worth disabling Office at least temporarily to see whether it helps.
It's also possible that your antivirus is interfering with the game, so try setting exceptions for TS4_x64.exe and Origin.exe, then repairing (again), in case an essential file is being removed or blocked. If that doesn't help, please let me know what antivirus you run.
