[RPi5] Libreelec 12.0.2 -> 12.2.1 no HDMI Signal on TV

Hello everyone,

I placed the update file from 12.2.1 in the \\Libreelec\Update folder and restarted Kodi. Now I no longer get a video signal. However, I can still access the folder structure via SMB on my PC. What can I do to get a video signal again? Or do I have to completely reinstall KODI?

How can I know what I have?

I have no extra card. I only have an RPi5 connected with a Liebe Grüße TV
