Engine crashes at launch

When I attempt to launch the editor it gets to ‘initializing… 45%’ and crashes

Unknown exception - code c06d007e (first/second chance not available)

Hello Systaltic,

Is there any additional information you can provide? What was the last thing you changed before this started happening? Was this from changing your engine versions? Did the project crash while you had it opening and now this happens when trying to reopen it? When the crash occurred, did you submit your crash information? Do new projects also crash when you try to open them or is it only this one? If it is just that one project, can you provide a log file from it? It can be found in the project’s directory under Saved / Logs

We haven’t heard from you in a while, Systaltic. Are you still experiencing this issue? If so, could you provide the information I requested in my previous comment? In the meantime, I’ll be marking this issue as resolved for tracking purposes.
