Problem with programming Lora discovery kit

Having a problem with ST-Link v2-1 programming the STM32CubeExpansion_LRWAN boards.

Have updated the firmware and using the latest driver for WIndows 10.

 

Programming requires constant driver restarting. Debugging from the IAR or Keil is nearly impossible.

On the several PCs the app ST-Link Utility can't connect to the board due to a USB failure.

Drag-and-drop feature works 1 time out of 100 with fail message: "The application file format is unknown and cannot be parsed and/or processed"

 

Thanks for help.
