GoPro Karma drone unresponsive after just 2 uses and over a year of storage

We bought this drone hoping to have a little fun with it...
We got in 2 sessions of about 15 minutes each in the first few months, then packed it away in its custom case.... Covid hot, then we moved... finally got a chance to take it back out, and the thing is unresponsive.
I looked online and a quick search showed that several people are having the same issue... he person shared that he had been using his drone regularly for just over a year when the problem occurred out of nowhere.
