CEC issue with RPi4 and LibreELEC 11

Hi

I am new here and I hope someone can help me

After installing and setup Libreelec 11 I have very often issues with CEC.

My old setup (RPi3>AV Receiver>TV) with Libreelec 8 runs perfectly.

But Libreelec on RPi4 (RPi4>micro hdmi/hdmi>AVR>hdmi TV) very often makes problems with CEC.

I have to turn off TV, turn on TV and hoping CEC is now working. But very often I have to reboot Libreelec, turn off AV receiver, turn on TV and turn on AVR and so on...

Is this issue only a "setting problem" or is it a cec driver issue/bug?

Attached my (german) settings:

PS:

sry for my band english

Everything works with the rpi3. Why not with the rpi4?
