dupassik Thanks for doing so much testing yourself and for providing a dxdiag. Since the dxdiag doesn't list any Sims 4 errors though, it's possible the game is being blocked from loading rather than crashing. That, in turn, can be due to an antivirus, so check yours for any recent actions involving the game. If necessary, add exceptions/exclusions for TS4_x64.exe, TS4_Launcher_x64.exe, and EADesktop.exe as well while you're there.
Please also double-check your antivirus settings, as many laptops come with an AV pre-installed that the user might not even know is there.
If that's not the issue, please create a new admin Windows account and try playing there. Make it local, as in, don't link it to your Microsoft account or any email address. (You can keep declining until you see some security questions instead.) Give the account a simple name, like Test; don't use any special characters. You won't need to reinstall anything in order to launch the game.
