This seems to work for now. But it will also break eventually

Thank you very much!
I have been looking for a solution for hours. How did you find it so fast?

YouTube really seems committed to blocking any third-party tool that alters its restrictions...

Is that octopus image exclusive to the Japanese version of YouTube, considering that the Japanese like to give everything a mascot? I haven't seen it on any European or American versions of the site.

I don't know. Check it yourself if you wish.
