My Apple Watch Series 5 won't turn on.

My apple watch dialed 911 three times yesterday. I took it off and now it won't turn on. I can get the apple logo with the two button hold, but then it just goes away and I get nothing. I've tried the youtube ideas--rubbing, tapping, button zapping, I put it in the freezer for 15 minutes and the time came up, but only for a few seconds. Also, there is a red lightning bolt. I have tried two different chargers.
