My wife has been trying since Feb. 2020. Then appointments were 3 months out. She showed up and was told that starting in March they had canceled all existing appointments because of Covid and she had to start again. She then made another appointment for August. When she went to go that morning, she found they had unilaterally changed her appointment to another DMV office on the other side of the city, which she couldn’t get to. So she had to make another appointment. She is now scheduled for early December.
May I ask what state you are in?
