There are many good suggestions here.

The one thing that stands out for me is that you have been doing this for 20+ years. Yet you say that the panic attacks only started a few months ago. What was happening when the early panic attacks happened?

Without further information some things that come to mind are: you got promoted to lead a different team; you are working for a different manager or company; management have shifted their focus; you have had some staff changes in your team or related teams; something in your personal life has changed, etc.

Finally is there something COVID related for you, your team or the company?

Too many questions. Helping with the panic attacks is an obvious first step. Removing or changing the causes of them is the long-term fix.
