[UE4.24.1] Crashing on boot

We recently upgraded to UE4.24.1, and I’m the only person on the team who is having this problem. I tried reinstalling UE, downloading a fresh workspace - nothing worked.

This is the crash I’m getting as soon as I launch UE:

Any help would be appreciated,

Thank you!

Tried updating all the drivers, verifying Windows files to make sure nothing is corrupted. Reinstalled UE, still nothing :confused:
