If your YouTube client is not working, it's not just you, there's a change from Youtube affecting a bunch of alternative clients like NewPipe on Android or FreeTube on PC, it's best to follow the relevant issues, wait patiently for a fix, and don't spam the people running these projects, because tbh it's not their fault, and also, they're doing this as volunteers
