UE 5.4.4 crashes as soon as I try to open a RVT material / material Function

[Tallosx66]

Working on RVT material / material Function. The Engine keeps crashing even if the material is not applied to an object. Simply opening the function crashes the Engine. Getting code:

Assertion failed: !UE::RenderCommandPipe::IsReplaying() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Renderer\Private\RendererScene.cpp] [Line: 5471]
