One really low-level test you can conduct is

1) Use “youtube-dl --print urls «video-page»” (feel free to use one of the
youtube-dl successors, like yt-dlp) to get the URLs of the direct video/
audio streams. Beware: they can look pretty gigantic.
2) Pass one of these to ffplay (part of the FFmpeg suite) to see if it can
play them. Or even VLC, if you prefer.

That just takes the browser completely out of the loop, to see if the
problem might lie elsewhere (or not).
