UE5 .2.1 and .3 fully broken

This shouldn’t happen from a technical standpoint (Referring to UE.) It would have to be something on your device. I mean maybe, I guess there could be something wrong. Try the following in order.

  1. You could try to uninstall and reinstall UE5 to fix any possibly corrupt files.

  2. If this doesn’t work, try rolling back to a previous driver version.

  3. If all else fails, get a licensed specialist to assist you.
