Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000018 when opening or even right clicking level
I've been working on a user interface and loaded a different level (double click). I skipped some files I didn't want to save and did some minor things in the other map. Then I closed the whole editor and took a break. After I started the editor again, I couldn't open my main level anymore (See the attached Log File )
I could manage to migrate the whole level to another project (also crashes there) and then I could indeed open the level in the old project one last time. I saved it again and now it keeps crashing when I try to open it (double click) as well as when I just right click (to do maybe another migration)
My whole master's thesis depends on this and I really need that state as I only have about 2 weeks left to do all the programming.
Altough the log files (the other log file is from the backup project) show different entries before the LogCrashTracker line, it's always the Exception_Access_Violation reading address 0x00000018 error.
Is there anything I can do to recover the state?
Kind Regards and Thank you,

Thank you for the sample project. I was able to isolate the crash to a "Get Game Mode -> Cast to CDGameMode" call in your FrontGate Blueprint (specifically the OnRep_Health function). Seeing as the crash is an access violation, it appears that it is trying to read the game mode before it has been loaded which is causing the issue. This is also why opening the blueprint, which causes the editor to recognize the game mode, prevents the crash from occurring. Additionally, if you set the game mode for your editor starting level to the CDGameMode blueprint, this will load the blueprint when the editor is launched and prevent the crash when opening your specific level.
