On my RPi4 2GB I've been testing and incrementally updating nightlies until LibreELEC-RPi4.arm-11.0-nightly-20220721-06fd018
Each update from LibreELEC-RPi4.arm-11.0-nightly-20220723-0008ab5 onwards, crashes the system.
Failed restarts eventually cause it to start in safe mode.
Having a look at the logs, I see a DBus error: org.freedesktop.DBus.Error.ServiceUnknown - The name org.freedesktop.UPower was not provided by any .service files
Other than that, I can see an error relating to missing html tags in Repository add-on repository.zachmorris. I have looked for that repository in my addons but haven't been able to find it though it appears to have something to do with gaming (which I don't do).
Crashlog is at:
Hope someone can have a look....
P.S. For clarity I should mention that after each failed attempt I restore a backup image of my working 20220721-06fd018 system. I have also tried different SD cards and a USB3.0 stick.
