Shaders turning pink on test

I’m new to VRChat and overall in Unity, I would like to upload custom maps I’ve made in the new SDK3. But I’m having problems with one in particular. It doesn’t have any textures besides the diffuse map but I would like to make post processing effects with LRP or HDRP.
I create the LRP as an asset, I put it in the graphics settings, It looks fine at first but everytime I update the project whether by installing or uninstalling new packages or testing a build in VRChat the graphics get back to default and turn pink.

I’ve tested LRP in a separated project, no post processing or shader graph and I get the same result.

LRP and HDRP is not supported in VRChat. You have to use 3D
