UE 5.1 Crashing randomly when moving objects in the world

Hello!
Im having an issue where the engine keeps Crashing when im moving Objects in the world.
it’s a map that never gave me any issues. today i had to change some things and the engine just crashes. i move a rock to the left crash. move a rock to the right crash.
i have the lastest Nvidia Drivers. tried restoring the Nvidia panel UE settings to default. no luck.
any idea what it might be?
i can play the game. i can edit BP’s it just crashes when i move stuff around the map or editing the terrain


Thanks in advance!

Hi Vyzor,

I see some mention of ‘Foliage’ in the crashlog, so I wonder if the rocks that you’re moving were placed with the foliage painter.

You can install ‘editor symbols for debugging’ (~60GB) to get a bit more information out of the crash log. But without C++ knowledge, this info may not be actionable.

One thing to try: You can ‘migrate’ (Right-click on map → Asset Actions → Migrate) the map to a new project and see if the crash persists.

I am struggling hard with this random crashes rn, have u solved it?

Got the same crash message when i tried moving an object even if it isnt placed with the foliage brush. Dont know what do to

Hi Oink Oink,

My advice is the same to you, if you install ‘editor symbols for debugging’ you’ll get more information about what exactly is crashing. (Instead of just Unreal_Editor_Engine, UnrealEditor_Foliage it will show what file/function call is causing it)

You could then use that information for a search, and potentially find more specific information about why it’s crashing or a solution.
