EDITOR CRASHES WHEN OPENING A BLUEPRINT (RIGVM ???)

[olzug]

The editor crashes only when opening a blueprint the error message is

“Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000008”

and it says stuff about RigVM a plugin or something but for some reason i dont know anything about RigVM and never installed a plugin like that. I found a sollution that could work

BLUEPRINT CRASHES WHEN OPENED

I have a project that uses the lyra sample in which if you open any blueprint it crashes. The strange part is that it started happening all of a sudden and that I can open blueprints normally if I don’t open the full blueprint editor. Is there any way to solve this? Here is the crash message Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000008 UnrealEditor_RigVM UnrealEditor_RigVM UnrealEditor_RigVM UnrealEditor_RigVMEditor UnrealEditor_RigVMDeveloper Unrea…

with the exact same error message and everything but just dont know how to or where to delete and re-install the RigVM plugin. Also the problem is only on this project and none of the other projects and i think the problem started with changing stuff with the unreal engine versions

That “unhandled exception” error is very generic, it usually says nothing about what was cause of error (and blame microsoft for that, or even Intel who designed this 8086 abomination of CPU some 50 years ago.).

Usually happens when there is invalid pointer somewhere (ie, something that should be there is missing)

So missing may be plugins, or they can have wrong version (build for different unreal minor version).
Or any dependencies missing. For lyra try to rebuild all binaries locally (but usually this fails).

Same generic error is not 100% guarantee that both problems are same.
