HELP: Instinct 2x Tactical Edition - no USB connection after update to v12.26

I updated my Instict 2x Solar Tactical Edition to v12.26 today. Afterwards when connection my MacBook Pro with the Instinct 2x using the delivered Garmin cable (USB-C to Garmin) my watch stucks in the connection watch face and is neither detected as mass storage device nor by Garmin Express Software. External hardware connections are allowed on the MacBook Pro. After disconnecting the watch the watch face does not switch back to the normal watch face. I have to do a manual soft reset on the watch to use it again.

What can I do?
