Changing scale to a Geometry Collection Component crashes the engine in 5.4

Development Programming & Scripting
1

I just ported my project from 5.3 to 5.4.2 and noticed that my destructibles crashed the engine. After some tests I learned that everything is working as with 5.3, but the engine crashes when it starts changing scale to this component, doesn’t matter if relative or absolute.

All collections I have give the same error. They are just some meshes that I destroyed in engine through the Chaos Destruction tool.

This is the error I get:

Script Stack (0 frames) :

Assertion failed: MParticleCollisions[Index].Num() == 0 [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Experimental\Chaos\Public\Chaos\GeometryParticles.h] [Line: 305]

The same happens if I rescale the actor that has the component

Same here… Did you find any answers?

It was also wen i opened a 5.3 project on 5.4.3 and rescale a geometry collection

Apparently it was fixed in 5.5
just waiting for the official launch

If changing the scale of a Geometry Collection Component is crashing Unreal Engine 5.4, it could be due to several reasons related to how Chaos Destruction handles geometry, physics, or certain limitations in scaling destructible meshes.

Got the same error, I can’t find a way clear the collisions properly.
Have you found a solution ?
