What happened?

While playing a video on YouTube, playback suddenly stopped. Even when I refreshed the page and tried again, playback stopped again.

I opened the console to see why.

Relevant log output if applicable

I think that log entry is unrelated (it is a warning not an error).

Issues like these can be caused by adBlockers or similar extensions (Youtube is fighting them).
What can help is :
a.) Clear the YT site data and cookies

b.) If you use uBlock origin, enable the experimental filter

It would be nice to translate the error message next time but I managed
"An error has occurred. Please try again later. Learn more."

What information is shown when you click "learn more" ?

I'm not using uBlock, I run AdGuard.
I can work around this locally (e.g. download/convert the video to MP3 and listen), so I'm not blocked — but I reported this because playback stopping randomly is a product bug and may affect other users.
My quick take: this looks like a YouTube-side/Firefox-compatibility issue that Zen is suffering from (Firefox often becomes the “stepchild” for some sites when engines diverge).

playback stopping randomly is a product bug

Could be very well caused by an ad blocker like adguard. Youtube tries to load ad in the middle of your video: fails to load it and runs into the issue and/or detects it's blocked.
