Need help getting camera to work on stock rom 20f coming back from Lineage 18.1

I need some help getting camera to work on stock rom 20f by dimm0k after trying Lineage 18.1 and didn't prefer it. The camera app would launch, show the camera UI, but the lens doesn't turn on and the app just freezes. I tried restoring my backup of 20f, factory reset, formatted everything and installed 20f rom clean. But nothing is working. Reinstalling Lineage 18.1 does bring back the camera, but fingerprint sensor doesn't work in Lineage so I'd rather stick with Oreo. Does anyone know how to fix this?
