Hi there,

I’am now have the same problem. If I delete a geometric brush. The Editor crash. Now the “build” doesn’t work anymore. With the same Error Mesage “assertion-failed-actor-brush”.

UE 5.1

UPDATE: Updated ver. 5.1 to 5.2 and it works. The crashes are gone when I’am deleting geometric brushes in world.
