can not connect my Fenix 5X Plus with Garmin Express

Since Sunday I can no longer connect my Fenix 5X Plus with Garmin Express

I did not change the Fenix or my PC

I have tested 5 different USB ports,
also on the back of the PC.
Uninstalled and reinstalled Garmin Express.
Different Garmin cables.
PC Restarted, off, disconnected from power.
Fenix reboot
Fenix reset
Garmin USB driver uninstalled .......

Nothing brought success

No connection to Garmin Express

If the Fenix is connected before starting Garmin Express,
Garmin Express crashes!

The Femix is only accessible via Windows Explorer,
but here only as a portable device not as a volume.
But this since the first day so while my Fenix 5X is displayed as a volume

Everything works fine on my Fenix 5X but no chance with the 5X Plus

System: WIN10 64
Fenix 5X Plus 5.10
