Opening a 5.1.1 project in 5.2.1 gives this crash:
The full error at pastebin: LoginId:xxEpicAccountId:xxUnhandled Exception: EXCEPTION_STACK_OVERFLOW - Pastebin.com
Any ideas? The documentation for RigVM is completely blank:
https://docs.unrealengine.com/4.26/en-US/API/Runtime/RigVM/
I turned on Editor Symbols for Debugging and the error is a little more detailed now:

Issue is now resolved. For posterity:
In my /config/DefaultEngine.ini file I had MatchSubstring=True
I removed that and now it works:
Thank you so much, this worked perfectly! I’ve been looking everywhere for a fix for this I would have never found the solution on my own!
