A few of us have had this issue since yesterday, trying all the proposed solutions. I've looked here, Reddit and Twitter and can't find a way to fix it. It's commonly on Game Pass but it's happened on Epic too.

A dev responded to another forum post suggesting deleting previous files but many of us don't have them in the first place.

Since this, I've attempted a repair, reinstall, deleting the folder in the user directory again, etc. This is annoying, since this game is the only reason I even renewed my subscription to my Game Pass.

I think this may be the very first time I've ever had a new game just outright refuse to even launch. Makes me glad that I hesitated on a pre-order.
