I was compiling my BP project, but during last compile it crashed and cant be opened anymore - it always sending reports to Epic. Is there any chance to restore data (BP mechanics especially) and transfer it to the new project, or it’s completely dead?
thanks

EDIT Solution for me:
create a new empty project
copy Content folder from old project into newly created one
create a new level, save it and restart the engine!
now you should open your blueprints, previously created levels, don’t forget to change GameState and other stuff in the project settings
The Blueprint (s) you were compiling probably was corrupted. I would try to move these files from the Contentfolder to some backuplocation and replace it by some of the autosaved or backuped older versions of the file (which should be in the saved folder) - just make sure the file were saved before the crash occurred. Sometimes, when something in a level got corrupt its also enough to not open the last level on startup or remove that level.
Try updating to 4.12.3 and seeing if you still have the same error.
Ensure that your graphics card drivers are up to date.
Make a copy of your project first, then delete the Saved and Intermediate folders from your project and attempt to open it again.
If none of these suggestions work, please provide the logs from your project’s Saved->Logs folder and also provide your Machine ID from the Crash Reporter window.
Hello Sean, I have installed the latest version of the engine, but an error is still there. I have done all the steps you described. Please find ID and logs
aaaand after reloading the newly created project for 5-7 times I have created a new empty level and somehow it’s became possible to open blueprints and run the project now with an older levels. So, I will accept your answer, but as a result it’s not clear what happened, why and how it fixed now)
