My level keeps crashing when opening or saving it but opens with launcher

MH53-BBP · December 24, 2023, 3:53pm

I’m getting this crash whenever I open my main level on a project I’m working on. I can get into the level when I launch the editor as it is the default, but other than that I can’t leave it and come back and I can’t save it under a different name or unreal will crash as well.

Does it crash if you open a new Level Map (the basic floor) ?

if not, then there might be an issue with these 2 objets leaking memory in your level map that causing that.

No not at all. I open my two menu maps and neither of them have this issue. But I do think I notice that my memory usage increases by simply having the editor open in that scene. But now I’m needing to figure out which two objects would be causing a memory leak to begin with.

Try to enable this Editor Preference > General: Performance > Show Frame Rate and Memory (it will also display total number of objects)

And Tools > Audit > Statistic to see all objects (you will need to refresh ingame)

At least these will give a hint where the issue might be.
