Unreal Crash: Assertion Failed

My project has all of a sudden started to crash in the following way: I do or add something to a level in my project and a moment later the editor crashes with the following report. After this initial crash whenever I try to reopen the level in question Unreal crashes again. So practically my project is destroyed level by leve.

Given the way this issue started appearing all of a sudden without me updating the editor or my workstation, installing plugins or making any major changes to my project I assume this has to do with a corrupted asset, but I have no idea which one it could be and how to track it down. Bulk removing assets from my projcet directory and reopening the project does not help.

Assertion failed: Export.ObjectName!=NAME_None || !(Export.ObjectFlags&RF_Public) [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\LinkerLoad.cpp] [Line: 4662]

If you install the editor symbols from the Epic Launcher, it would help get a better idea of where things are crashing and perhaps why. Once you install them, the output that you pasted above will have much more detail in them when a crash occurs.

Thanks! Done!
