Materials Recomplile constantly

Hey Guys,

Since I got a new computer, I have a strange issue when working with Unreal Engine.
My Engine always wants to recomplile the Shaders when I add a node in the Material Editor. For an empty Project it is always around 100-300 Shaders and I dont know why I get this problem.

Has anyone had this kind of problem ?

PC Specs :

NVIDIA Geforce RTX 2070

AMD Ryzen 7 2700X

32Gb Ram

Windows 10 Home vers. 1809

Happens in all Engine Versions for me

I have the exact same problem but haven’t found a solution yet. Even just opening a material causes the Editor to recompile everything again. Do you have a clue yet?
