I can create a “decal projector” by right clicking on the project => rendering
Is it this ?

You want URP Asset with Universal Renderer

Yup - if you created all your materials in builtin you ned to update them to URP
There’s a menu item for it which you can try.
Are you using source control (like git) ?
Oh, found

I need to update all of my materials
by user 224464722878005248
No material at all ^^’
by user 224464722878005248
Did I need to create an issue ?
by user 224464722878005248
If you can yes, please make a new scene with just the shader and one object with your material (it should work in Unity of course 
)
Okay I will try it
by user 224464722878005248
Ok, you know what ? I’m dumb 
It was only because my ExportShader Tag disappear after converting material ^-^
So SORRY for bothering you
It works fine
