Black screen after update to 9.2.3

Hello @ all,

at first i wanna thank all devs for this great software.

Unfortunately i did an update from 9.2.1 to 9.2.3 and after reboot the last thing i can see is the waiting for network and the libreelec logo, and then the screen goes black.

I made no changes on config Files.

Before update all but hdmi cec worked fine.

Using multiple Profiles (kid/parent) with sql db on qnap device

System:

rPi 4 4gb

sdcard boot

LAN

Original 4b power supply

Hello CvH,

no, i made no hardware related changes. I just made updates from within Libreelec GUI, for libreelec itself and the firmwares for example.

Now i try to find out how to get the profile and network share settings from the broken system to rebuild from a new installation.

At the moment the broken system is untouched.

/UPDATE:

I changed the hdmi output from 2 to 1 on the raspi4 (counted from the power plug) and started the System again.

After a while i switched the TV on and...

Kodi 9.2.3 was running!!!

Thanks anyway for all ppl trying to help!

/Update end

Best regards,

Horstworst
