Multiple Camera systems in unity 6 build

I have a Virtual reality project. We updated to the latest Unity 6.0 updated and our regular multiple camera system doesn’t seem to want to work in build mode. We have a PC screen camera with a higher camera priority than the OVR camera rig. The idea is that the PC camera provides a flat screen perspective for a PC user and a quest link VR player. This works in earlier unity 2022 and 2021 builds. I was wondering if anyone know of any updated unity settings which might influence camera priority. Either for the editor or XR settings. The builds seem to always prioritize the VR camera regardless of camera priority set in the editor. It works as expected in editor play mode but not build mode.
