Newly developed stutter?

Newly developed stutter? In middle school and early high school, I was very talkative and known as the class clown. Then the pandemic happened, and I just stayed inside and barely spoke to anyone. Since then, when I try to talk to someone, I'll accidentally talk to fast and slur or stutter my speech. I speak fine when I'm singing, reading, or thinking though. Before, I just accepted that I'd talk like this from now on, but ever since I started my first year of uni, it's been bothering me a LOT. Sometimes, I'll want to say something or make a joke but won't because I know I'll mess up the delivery. Is it possible to make a full recovery? If so, how long would it take?
