Cast devices freeze when casting audio streams

I have an issue with casting some third party audio streams. I have relied heavily on https://developers.google.com/cast/docs/player and followed those instructions on how to create a custom receiver for playing the streams.

After just a second or so after starting the stream (I don't get any sound) the Cast devices freezes and they stop responding to debug via Chrome and they don't react to stopping the Cast session. Often they are so locked that even issuing a reboot via the Home app doesn't work; I have to physically disconnect the power.

It's the same behaviour on Chromecast v2 (1.22.79313), Chromecast Ultra (1.22.78017) and Google Home (1.22.78295).

What could the cause of this freeze be? Is this caused by some very broken streams? Is it a known issue? Are there any workarounds? Shouldn't one expect the Cast devices to handle this and give some error message and not crash like this?

This is the log I get from the Chrome Developer Tools before the connection is reset:
