Re: Sims 4 will not start after installing new graphics card

@agastopia  The unrecognized video card error is irrelevant here.  Your 3080's device ID hasn't been added to the game's database yet, but as the message from Steam says, your graphics settings are set to something reasonably high anyway.  If you'd like your card to be recognized, you can use the file provided here, which does include the 3080:

However, please put that aside until Sims 4 is up and running, since it's not a critical troubleshooting step.

The game not loading in Origin is a separate issue entirely.  Please let me know what antivirus you use.  And if you've enabled Controlled Folder Access (or it's enabled by default), please either disable it or set exceptions for TS4_x64.exe and Origin.exe.
