Compiling shader become slow

Hello !
I have an issue with shader compilation in 4.26.
It works well before (and my project is quite old !) but since last week, when I have to compile something even like 1000 shaders it takes a really long time !
It is compeletely stuck, and I can’t do anything at the same time or it will block completely the project.

I have a great PC, GTX 3080, and I NEVER had any issue (it was very fast before) and now, compiling 1000 shaders take much more time than compiling 30 000 shaders before…
I haven’t done anything special… Just last week I decided to build all my maps but it as nothing to do with it… (the problem occurs even with a blank map when I open materials…).

Is there anything I can do ? Maybe something is just full ?

Thank you for your time !

All the best

You could try to clean up some of the files that could have become corrupted. Simply go into the project folder and remove the: Saved, Intermediate and DerivedDataCache folders. I suggest putting them somewhere else.
