Generally when browsing using orion, I have tracking prevention and content blocking enabled. For YouTube however, I do not mind watching some ads, especially on videos of creators I like. For that reason I disabled content blocking for youtube.com (while keeping tracking prevention on). For some reason, YouTube is still not playing any ads and now it shows a notice that eventualy playback will stop working alltogether. I understand this might be something you cannot do anything about, and that youtube has user tracking and ads connected in such a way, that without tracking you don't get any ads, even "unpersonalized" ones.
Although the screenshot is in Czech, basically it says that after 3 more videos, the youtube player will stop working since I have ad blocking enabled (I do not).

Anyways, thanks for (possibly) looking into it and also thanks for the great work on kagi and this browser as well.
Ads would play before/during videos, but tracking prevention is still enabled.
