Camera model
RPi Camera Module 3
What is the problem?
The control page shows "Webcam stream loading" in the viewer forever.
What did you already try to solve it?
Power cycle of whole system. Also checked to see if the camera was recognized at the command line:
supported=1 detected=1, libcamera interfaces=0
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
Nope

Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
Raspberry Pi 4 B, browsing from Mac OS & Safari. Was working fine before I reflashed my card to update Python. I restored the previous setup from a backup (using OctoPrint's backup/restore).
Someone mentioned that the legacy camera lib might no longer work, so I tried rpicam-hello at the command line and indeed it said no cameras detected. So I went into config.txt and turned camera autodetection on, then rebooted.
Now rpicam-hello reports finding the camera, but the OctoPrint stream still doesn't work. Here's the output; I figured the last error was because OctoPrint is using the camera, but I don't know...
