This is a big concern for me. I thought Apple is a serious company and look after their customers complaints. The issue occurred yesterday and I can't imagine using my mac without bluetooth as I use my AirPods to talk with clients and attend meetings on Zoom. I have tried everything whatever is there and the only thing that comes to my mind is now to roll back to a previous version - It is quite a task but it's better then waiting and relying on Apple to do something as I have noticed it's been almost a year since this bug started and Apple has not commented officially when they are going fix it!
