SOLVED: Constant crashing on 10.9.2 w/RPi4

[WWWR]

Since updating to 10.9.2 with apt on RPi4, constant (every two minutes) crashing of the JF backend.
Have reinstalled twice, once with a total reinstall of the OS.

Is the RPi4 just no longer supported?
If so, how can I easily roll back to pre-10.9.x? It's been a total technical disaster since 10.9.x.

Thanks for any info on this.

Possibly solved: simply running 'sudo apt-get install --reinstall jellyfin jellyfin-server jellyfin-web' once JF was already installed (and crashing) on the new OS install has made it run for a solid 10 minutes so far, longer than it ever did since 10.9.2.

Hopefully this helps anyone else on RPi experiencing a similar issue, perhaps there is a problem with the installer.
