Crash when starting the editor from a CodeProject

Hi there,

I was just messing around with BlueprintInterfaces. At some point I needed to change stuff in an interface I already had implemented (I did not need it to return something any longer). However, I still had a return node in my implementation, which I could not delete. I just decided to try to recompile things and see what happens. Well, something did happen, but something I really did not expect: On restarting the editor it just crashed loading UE4Editor-Engine.dll

Callstack:

Access violation - code c0000005 (first/second chance not available)

Fatal error!

VisualStudio Debugger Exception:

Unhandled exception at 0x000007FEDA045811 (UE4Editor-Engine.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0x0000000000000058.

Any ideas on how to fix this?

Hi Cronk,

What version of the Editor are you using, and are you using the binary version installed by the Launcher, or did you build the Engine from source code?

Is this issue only occurring with one project? Are you able to reproduce it in a brand new project from one of the templates? If so, can you tell me exactly what steps you took from creating the project until the issue appeared?

Hi Cronk,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.

Thank you.
