One argument for occasionally going to a class, aimed specifically at people who practise alone.
After two years of following videos you have almost certainly drifted into some habits, and you cannot see them. Nobody can see their own alignment, and a video teacher cannot see you either - that is the one thing the format cannot provide. A class every month or two, or even a single private session, is mostly about someone telling you the two things you have been doing slightly wrong for a year.
What you tend to find out: which side you favour, that one shoulder does something the other does not, that a pose you thought you were doing is a different pose.
It also gives you material. Teachers sequence in ways you would not think of, and one class often supplies a month of ideas for your own practice.
If classes are not available, the home version is to film yourself occasionally. Set the phone on the floor for one sequence and watch it back. It is unpleasant and it is the same information - the gap between what you feel you are doing and what you are doing is usually large, and it is invisible from the inside.
Neither is a reason to keep following along. Build the practice; use the outside view to calibrate it.
