nRF 52 DK cannot connect with Bluetooth low energy app on nRF connect for desktop

Hi 

I'm having trouble when trying to connect nRF 52 DK with BLE app on nRF connect for desktop.

I can select device of my nRF52 DK, but cannot not scan any discovered devices, like the picture shows, 

  

because of the problem shown below,

 

  • Note: Adapters with Segger JLink debug probe requires MSD to be disabled to function properly on MacOS and Linux. Please visit www.nordicsemi.com/nRFConnectOSXfix for further instructions.
  • Getting information from J-Link debugger...
  • Found device type: unknown. J-Link firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Jan 20 2022 16:43:31.

I've check this website www.nordicsemi.com/nRFConnectOSXfix, and tried to disable MSD using JLinkEXE(J-Link commander).

Then I tried to reconnect with BlE app, but it still doesn't work. How can I solve this problem?

Thanks a lot in advance for any device.
