Recently I updated my system to LibreELEC-RPi4.arm-11.0-nightly-20220903-97c088f
and later on I also verified this issue with a complete new vanilla installation w/o any custom Add-Ons installed nor any custom settings.
When I try to play back a css-DVD on that machine, the DVD starts rotating, then the rpi works for a while on it (blue moving circle shown on display) and then falls back to the main menu.
I tried it with three different DVDs and I can verify that in July, DVD playback worked great with the very same components and libreelec.
I also updated the kodi log here.
