BluePrint Corrupted, Crash when opening Project
Hello, I Have Been Working on a small project Based on BluePrint, When a BluePrint (ResistanceWeapon) stopped compiling whitout any changes to it or to any other blueprint related. Without saving i closed the project and reopened it. Unfortunately All my BluePrint Related to ResistanceWeapon, and ResistanceWeapon itself were now Corrupted. At this point, Start Playing or Right/Left Clicking any of those corrupted BluePrint in the Content Browser made the editor crash.
I Tried Setting bRecompileOnLoad to False in BaseEngine.ini but my BluePrints were still uneditable.
I then tried many things. Creating a new project and Importing old backups of my blueprints with bRecompileOnLoad to false gave me the chance to edit them. But they couldn't compile, Some of the Variables i made appeared in the graph but couldn't be found in my Variables list. I Deleted those variables in the graph, but when trying to create new ones with the same Name, the Editor told me i couldn't because a Variables with the same name already existed.
After Deleting all parts of the BluePrint that communicated with other blueprints, i then recompiled it and those "Ghost" variable still weren't appearing, couldn't be found with the search tool, but the Editor still told me they existed when trying to create new ones.
So i Created a brand new project Extending on the ThirdPerson BP. Created brand New BluePrints, And Remade the hole project based on some Copy-Past and Remaking some stuff. There i Encountered a new minor problem. Input Command inside my BluePrints extending actor did not respond anymore. I just went around this problem by Puting Inputs Inside "MyCharacter" BluePrint and making them communicate with the blueprint extending from Actor.
At This Point all my Project was back and running. All worked perfectly fine. While remaking this new project i exited the editor multiple times and got the time to manually make a backup of the project from the document Folder.
The next day (Today) i Turn on the computer, and open my project. Editor instantly Crashes. I open the manual Backup i made, Same Thing. I Try Removing "ResistanceWeapon" Project opens (but obviously dont compile due to references to ResistanceWeapon of other blueprints)
I Linked the .uproject and all the Blueprint I Modified or Created from the project from the save i made yesterday when everything were working like a Charm after Copy/Pasting, Recreating everything. When Crashing the editor always display nothing else than : "We apologize for the inconvenience. Please send this crash report to help improve our software."
*Edited, with Log of current Crash and DxDiag
Was "ResistanceProj" a class that you had defined and maybe removed or renamed? Or maybe you didn't include it in the .zip that you provided us?
I did find and fix a crash, but it looks like it resulted from not being able to find a class type that used to exist (specifically regarding the "PM_Slot" variable).
Either way, thanks for identifying this crash. Users should be able to remove/rename classes without hitting a crash.
Cheers - MikeB

Would you mind providing the assets in question? Unfortunately, there's not a lot to go on in the log!
