I know this is quite an old thread, but in case anyone was looking for a solution that I stumbled upon, this is:

Specification: Unity 2022.3 LTS
Pipelines: URP
Build settings: PC, SteamVR

When the problem occurred: After turning on the second camera (even on an empty stage)

What caused the performance drop: added Screen Space Ambient Occlusion in RendererFeatures.

Solution:
I duplicated AssetRenderer and disabled Screen Space Ambient Occlusion for it. In the Render Pipeline Asset, I added a duplicate AssetRenderer to the RendererList. In the second camera, in the Rendering section, I set the Renderer to the duplicate one. This allowed the first camera to have Screen Space Ambient Occlusion and the second not.

This solved my problem. I hope I could help someone (even myself from the future if I forgot :D)
