Actually it might be better to just post logs from a plain LE/kodi installation - that won't have any personal info and will rule out issues due to setting changes as well.
If you have a spare SD card write LE 9.2.3 to it, if not simply stop kodi, rename the .kodi folder to .kodi-bak and start kodi again (and later remove the newly created plain .kodi folder and move .kodi-bak in place again - with kodi stopped).
Edit: to create the logs, enable debug logging and kodi and then power off the pi, then start up again - that should make sure the CEC connection is started completely "fresh" (at least from the RPi side).
so long,
