I use the Firefox extension Untrap on my PC, and every time I go on Youtube it says the extension’s slowing the browser down. I use Invidious on an old tablet when I go to bed, and I just have to refresh now and again to get it working, but there are far fewer instances on the list, I’ve noticed.
You could use pad.riseup.net as a perfunctory solution. It’s just a text file that anyone with the link can edit, but Riseup is privacy-focussed.
