OSMC's October update is here with Debian Buster and Kodi 18.8 - OSMC

Hello
I have problem booting after upgrade to new version - after installation and reboot I saw only black screen. I think that something went wrong and completely reinstall system. On clean system I´m continue with installation of @joakim_s X11 simple desktop.
After installation of this I can´t find in Program Addons X11 launcher and after reboot I saw again black screen. It is possible to connect to RPi over SSH and I have these logs: https://paste.osmc.tv/doluzeyuwe
After some time when I move with mouse I saw this picture


When I tried

sudo reboot

actual session was closed but raspberry not restarted
After unpluging of power I saw again the black screen and these logs: https://paste.osmc.tv/uxewokosep
Strange is, when I testing this [TESTING] Debian 10 Buster
all working good, but after official update i have these problems.
Anybody have same problems?
I known that X11 simple desktop is for stretch, but I dońt known why is broken also booting and how to uninstall simple desktop or fix this problem.
Thanks for help
Jan
