Wasn't there some fixes in the nightly builds released after 12.0.1 regarding some issues in conjunction with DENON AVRs?

RE: RPi 4/5 + Denon AVR - 4k60 'No Signal' issues
[…]
I have now been running 12.0.1 for a week and have switched my Denon AVR-X 3600H on and off about 10 times, switched sources as well numerous times.
I am pleased to report the issue appears to be fixed. I am running 60FPS 3840x2160 output in settings and it has reliably always displayed since updating. I have not had to reboot the Pi or switch sources to force output.

JohnWayne111 , which version of LE do you have installed? Already tried with a recent nightly build for a cross check?
