AI Summary: The engine crashes when a `Reflection Probe` or `Camera` actor, which utilizes a debug renderer, has its scale set to 0 on any axis. The crash occurs within the `FQuaternion::ToMatrix4` function during the calculation of the unscaled model matrix in the debug scene renderer, leading to an engine freeze and crash.
