HRM not working after Zwift crash

Garmin HRM / Windows 10 / Bluetooth

Had this happen 2x. Zwift freezes. Shut it down then restart Zwift.

Smart Trainer reconnects fine.
Garmin HRM is found and says connected but no data flows from HRM to Zwift.

Try to disconnect HRM from the Strap and wait for about 10sec for HRM to stop working (sending signal) before you reconnect. I do this before i enter Pairing Screen.
