Some links shared to the plugin fail to play, stuck at busy spinner, no error cause in log

Context

Please provide any relevant information about your setup

• Add-on Version: 6.8.18+matrix.1
• Kodi Version: 19.1
• Kodi GUI Language: EN
• Operating System: LibreELEC 10.0.0
• Operating System Language: EN

Expected Behavior

Any links shared for playback via the plugin://plugin.video.youtube/uri2addon/ path/endpoint should either play, or an error message (preferably, detailing the reason) should be shown within a reasonable amount of time, 10-30 seconds.

---

Current Behavior

Sharing some (in principle valid) YouTube links causes the busy spinner to be displayed for many minutes. One time I was shown a nondescript error message (item failed to play, check log); on reproduction the spinner is going for more than 12 minutes now. When I press 'Back', the "item(s) failed to play" message is shown.

There is no information either shown in UI or in the logs that would detail what's going wrong.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Share https://m.youtube.com/watch?v=BeT_reBoruI&list=UU8aSR_qI6MCIJkGJfPn1RvQ&index=4 for playback, using Yatse on an Android device or Chorus / The Lab, Player.Open, params:{"item": {"file": "plugin://plugin.video.youtube/uri2addon/?uri=https%3A%2F%2Fm.youtube.com%2Fwatch%3Fv%3DBeT_reBoruI%26list%3DUU8aSR_qI6MCIJkGJfPn1RvQ%26index%3D4"}}
2. Watch spinner

Log

Isolated log of reproduced error: https://paste.kodi.tv/efocavexad.kodi

Live log of first occurence: https://paste.kodi.tv/jogajuvori.kodi (this one is much less readable, as I was queuing the video in question while another one was playing)

---

Additional Information

Processing this request takes a wrong turn somewhere on the uri2addon side of things; playing the same video with plain plugin://plugin.video.youtube/play/?video_id=BeT_reBoruI works as expected.

This issue is seen in Kodi, running on OSMC. Youtube plugin v6.8.18+matrix.1, Kodi v19.1 running on RPi3 and on RPi4. This ticket is possibly a duplicate of https://github.com/anxdpanic/plugin.video.youtube/issues/248

I'd like to clarify (concerning the possible duplicate): I only see this type of link not working, I have a hunch it has to do with a list/index parameters in the URI.

I do not experience any of the other symptoms mentioned in #248. I can navigate the menus fine and also share by (only) video_id for playback, I'm not aware of any other stuck busy loops. The "My Subscriptions" menu item takes a while to load, but that's nothing new - it became slow for me after it was switched from API to RSS quite a while back, from what I understand.

Yesterday, after reproducing this issue, I saw that LibreELEC 10.0.1 was out and upgraded, no change at all for me. I'm on x86_64-Generic; a dedicated i5-based HTPC.
