Badsize on PlayerStart anywhere in the UE Map?

I’ve been using UE for some time and I downloaded version 12.3 today. After updating my project I opened the main map I was working on and suddenly my player spawn doesn’t work. (It did work in version 11)

No matter where I move the PlayerStart in the world I get the “BadSize” error. I’ve checked collisions, I have no hidden blocking volumes and I am at a complete loss as to what is causing this error.

Any help would be greatly appreciated.

Cheers

Did you end up fixing this?
