I have a similar trouble. The first two months I had my Airpods they connected and stayed connected fine with Zoom. About 2 months ago, they started dropping during Zoom meetings only, and have poor sound quality. My bluetooth headset doesn't have this problem, and my Airpods (pro gen 2) connect fine to everything else on my computer or phone. It's embarrassing to be in a meeting and all of a sudden not be able to communicate.
