When exiting AR while using Post Processing - 'No camera in scene found or available yet - can not create postprocessing effects'

[ROBYER1]

Describe the bug 💬

I have an AR Demo project, you can also find it here but you need to update to Needle Exporter 2.67.0-pre: https://github.com/ROBYER1/Needle-AR-Demo

When entering and exiting AR in this project on mobile or desktop, you get this error: 'No camera in scene found or available yet - can not create postprocessing effects' I also get some endless console spam of this after exiting AR: '1 Layers {mask: 1}'
