I have also started seeing this issue on my Onkyo TX-NR525. Thanks for the quick work on a fix. It may be worth noting that I only see these errors if my Onkyo was active/on at the time that I restarted HA.

Unfortunately, my TX-8050 Network Receiver (not an AVR, just a stereo) 2011 model year, crashes even with this patch. I grabbed the older component source (pre 0.82.0) and dropped it into ./config/custom_components and it works for my older receiver.

The symptom is that it totally crashes the network remote control on the receiver. Have to unplug and replug in the receiver to reboot the internal CPU.

The diffs between versions are pretty complicated so not sure where to start trying to track down the culprit but this PR didn't solve the problem on my TX-8050.
