Objects turn all black when upgrading materials to HDRP

I am using the Low Poly Modular Terrain Pack from the asset store for this, but i dont think thats the problem. When i import the High Definition RP package into my scene, everything turns pink-ish. I was then told to upgrade all my materials to support HDRP. For everyone else that seemed to be the fix but for me all my in-scene objects turn black. Is there any fix to this?

The shader for my materials are set to HDRP/Lit and the base map is still set to the correct material. But the object still appears black. Also idk if this helps but my Baked Global Illumination is turned on and set to shadowmask.
