If you are still looking for a working public invidious instance:
https://inv.nadeko.net
- generate your own visitor po tokens and add to preferences (https://git.nadeko.net/Fijxu/invidious/wiki/Generate-a-po_token-and-visitor_data-for-inv.nadeko.net)
- pick the backend that works best (to me 1 the main one)
