Can you provide more information about when this crash occurs so that we can try to reproduce it on our end?

Also, please provide as many of the following as possible:

Your dxdiag (Windows Start Button>(search “dxdiag”)>Launch dxdiag>select “Save all information”>attach text file to your post.)
If the Crash Reporter window is present when the crash occurs, select “Copy Callstack to the Clipboard,” and paste that information in a document and add to this post. Be sure to hit “Submit” on the Crash Reporter pop-up to send the Crash Report to Epic. Also, be sure the text includes your machine ID.
“UE4.log” Located: Engine\Saved\Logs\
“ProjectName.log” Located: ProjectName\Saved\Logs\

Providing this information and appropriate logs will help us track down and isolate the source of the bug as quickly and efficiently as possible.

In regards to recovering your project, you can change your default map to “none” in the DefaultEnging.ini. When you open your project it will open to a blank map at which point you can open/load your latest saved map from the Saved folder in your Project Folder. Alternatively, if you can identify the last Blueprint asset you were working on in the Content Folder, you can delete it and right-click/open your .uproject without out.

hi, using the trick on the defaultEngine.ini the project now opens, but gives me a bunch of errors,
as attached on the picture. if i try to open any of the critical blueprints, the editor crashes.

i think it may be related with the proiject previously being open with a source engine version… but that may be completely baseless.

in any case, if i try to fix up the redirectors, it crashes too.
