Error when opening project?

I had just closed my project and had clicked open in the Unreal Launcher and it crashed without opening the editor saying this:

!Id:c23d341b3bbbd9cce9db0d1a7f0b2447

No minidump found for this crash.

Does anyone know how to fix this?

Hey -

Thanks for the report. If you could go to the Troubleshooting Launcher Problems of the Epic Wiki page and submit your DXDiag and logs, I can pass this on to our investigation team for review.

Cheer,
