I tried the recent nightly LibreELEC-RPi4.arm-11.0-nightly-20220213-fcba5db and notice it's rebooting every 20s or so.
I've Upgraded to previous nightly 20220212 in order to see logs but that to crashed also and has gone into safe mode. I'll paste the log.

Update 15 Feb 2022
I just updated to LibreELEC-RPi4.arm-11.0-nightly-20220215-8a018bd from LibreELEC-RPi4.arm-11.0-nightly-20220212-d203600.
I'm seeing similar to LibreELEC-RPi4.arm-11.0-nightly-20220213-fcba5db.
Kodi is rebooting every minute or so and eventually going into safe mode.
I've pasted another log link here. http://ix.io/3PDH
