Thanks for the info, aside from “game drive” confusion your spelling and lucidity are great.
I did a search for “Adapter->CreateCommittedResource(Desc, GetGPUMask(), HeapProps, InCreateState” and found this thread where the problem was coming from some GPU tuning application.
‘Verifying Files’ in the ‘Manage’ menu of UEFN + Fortnite is always worth trying.
Creating and opening cinematics in a new project would help determine if this problem is more related to the state of your hardware (GPU crash) - or an asset problem. (Sequences that were created in previous versions of the editor are now problematic)
