After adding a Cube to the Viewport and creating a Geometry Collection the Editor will crashing in the Vulkan RHI. This crash does not happen in DirectX or if the Geometry Collection is made before dragging the Cube in the Viewport.
This was reported and tested in 4.24 Preview 4 (CL-10387632) and reproduced in Main 4.25 (CL-10487445)
Results: After naming the asset, the Editor will crash.
Expected: The Editor doesn't crash
