Blueprints have begun to crash the engine if touched, clicked or trying to read it. Always getting the same error.
I can’t do anything with this project anymore, just crashes every time.
Even though all other projects work fine, I verified the engine files.

All I did here was:
- Loaded the editor
- Double clicked “BP_ThirdPersonCharacter”
(A character blueprint I edited from the original)
A re-imported version from the template works, but I have forgotten everything I did to it.
Everything worked fine til some point where I opened the project again and couldn’t open blueprints anymore.
Note, I even tried diffrerent engine versions of the project.
