I was editing a collapsed graph, and deleted some nodes. I undid the deletes and everything came back. I went up to the event graph, and saw I had a few errors popping up. I compiled to get rid of them like normal and the engine crashed to desktop. Tried to open my project again from the launcher and got a crash, I crash every time I open the project. I really need to try and get this back.

Hi esquire, I’ll be looking into your issue. In the meantime, could you find and post your LOG and DMP files from the crash?

Even though you hit undo, it looks like a reference for one of the nodes is missing. Try this: - Make a clone of your project. - Go into the project through Windows Explorer and move the .uasset that you were working on when the project crashed out of the project. Don’t delete it, just move it. - Try to load the project. - If it does load up, try moving the .uasset back into the project. Let me know how that goes. ---

\Well that worked to get the project open. When I moved the asset back into the project it showed up. When I tried to open it, I got a crash again. So its definitely my characters BP graph. I couldn’t attach the logs because it said .log wasn’t an allowed file type and .dmp had no such upload. Thanks for the super quick help. Any ideas on how I can get back into that graph? Or can I try to find an autosave of that specific asset? ---

As long as you zip the log and dmp files they should upload fine. You can see if a backup of the blueprint was generated. Just make sure to copy/paste them so not to lose any backups. :\Users\YourName\Documents\Unreal Projects\YourProjectName\Saved ---
