Description

From a user report:
It happens after I play the game in a new window from the editor. I noticed it may be related to building collisions for a point cloud on runtime:

[Link Removed]

If I don't build the collisions UE stays stable, but if I hit play, with building collisions enabled, after I close the PIE, UE crashes after a few seconds.

Also, it seems it has to do with aborting the collision building on runtime, while building I get this banner:
[Link Removed]

And if I close the PIE while building, it changes to:
[Link Removed]

and a few seconds later UE crashes.
