BLUEPRINT CRASHES WHEN OPENED

Development Platform & Builds

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

Hey there @LeMans_66 and @TomHowzzat1! If possible, could you enable editor symbols and see what the crash context says after we can read the full stack?

Also, here’s a thread with 2 possible solutions:

One involves checking to see if the plugin was disabled and reenabling it.

The other involves removing the RIGVM plugin, then reinstalling it, however I would back your project up first as this could cause larger issues.

@SupportiveEntity Thank You So Much!

Disabling and re-enabling the plugin worked, i’m so happy that you helped me out!

Thanks for helping
