Attempting to Migrate a project from UE 5.0.3 to UE 5.1.0.
It Crashes and I get the following error message:
EDIT:
Installing Debug symbols for error report now this should definitely help me figure it out.

Found a few threads in the past for this exception error. However the solutions seem broad and unhelpful as I’ve tried a few and the issue seems to persist.

I loaded up a similar project or two and they seem to work perfectly fine. So it seems tied to this specific project. Not sure how to proceed any advice much appreciated.

UPDATE:
Got the exception undated to show bugs, problem is I don’t recognize any of these .cpp files as things I’ve worked on or in so I’m not sure why they’re throwing these errors
The only thing I can think of from looking at the first file is it may be with Actors

SOLUTION FOUND:
There was old starter content in my game that had .umaps in it that had conflicting issues.
After deleting them in my 5.1 project it loaded without issues.
