Fenix 6x / Windows 11 - "There was an error syncing with Garmin Connect"

I cannot get my Fenix 6x to sync thru Garmin Express in Windows 11.  I have tried everything I can.

Garmin Express recognizes the Fenix watch, and then indicates it has "Items Ready to Install", but when I hit "Install All" the progress bar makes it about 25% across the screen, and then stops and displays "There was an error syncing with Garmin Connect".  This happens every single attempt.

I have tried (from reading thru other's difficulties):

  • Removing and reinstalling Garmin Express
  • Rebooting the Fenix watch
  • Rebooting the Windows 11 PC
  • Tried many different Garmin sync cables
  • Within Garmin Express - "Clear Upload History" for the device
  • On the PC deleting the sync folder within C:\ProgramData\Garmin\CoreService\Devices\xxxxxxxx

All of these steps are to no avail

Is there possibly a file on the Fenix device itself that is corrupt?

Please help.  I am stuck.
