Material Editor Shader Compiling to Slow

Hello,

System:

   Intel Core:  i7 6700HQ 2.60GHz
   RAM:       8GB

I have a problem. If I make a material it takes to much time. If I make any change like a parameter
it takes maybe 30 second and i have cpu usage of 100%.
4 shadercompileworkers are starting.

I can’t spend hours for making some easy materials.
Right now i try to jump back to 4.19 and hope its enough. On earlier versions i had no problems, but it cant be the solution and i hope i can downgrade the project.

best regards
Stephan

PS: With 4.19 its much better but i have to remake everything because the project was made with a higher version.
this will take some time

Now i tried different engine version, and the idea came up to uninstall the substance plugin.
And this works well, the materials work as expected and speeds up everthing.
