I have been a bit limited in the time I can spend lately trying all other SF versions, I can go back to 6190, I don't recall which other version I tried, but it was a no-go.
If it is affecting all the way back to 6190 then Google figured out how, or changed something, to stop it from registering in SF, using the last known working method of logging into Chrome.
As I said, seemed it stopped working even longer trying to do it with Edge, I tend to use Edge over Chrome. But I did have SF login set up with YouTube back on or before the date of the last post was posted about issues, so somehow it now got disconnected.
All my other logins, right now, thankfully, work. Netflix, Peacock, and Amazon.
I wanted to add I knew others who had issues with Facebook login with another app, but you could easily save the cookies from the login in browser to a txt file and that would work.
I did try replacing the cookies.txt file SF makes with cookies.txt from YouTube in Chrome, created with an extension in Chrome, but that was a no-go as well.
