When start QGroundControl, lose connection with the drone.

Matek H743 Slim V3 controller
Radiomaster DDR4 receiver
Radiomaster TX16S control panel
Radiomaster Nomad control module

ELRS 3.6.0 control firmware

MAVLink control protocol

WIndows 11 ground station operating system
Connect the Nomad to the ground station via USB

All telemetry and control is transmitted perfectly when working with Mission Planner, but as soon as I start QGroundControl, even without pressing the Connect button, the connection between the drone and the controller is lost.

I have reinstalled QGroundControl and reflashed all modules with the latest version of ELRS. The controller is flashed with the latest version of EdgeTX.

I do not understand what the problem is.
