Collab Gray Scene HDRP

I am using Unity 2018.3.of2. I am using a collab file for school, which I share only with myself. It's using HDRP, both of which are installed on both computers which I use with this file. When I open it at school, it's working perfectly, but on my home computer, I get a completely gray scene view, and an all black game view. This is the only collab file (which makes me wonder if its an HDRP issue) where this happens. At home I am still able to add assets, edits materials, etc. but I'm essentially working blindly, because even material previews are grayed out. Any help is appreciated! Cheers! :)
