The Jlink on the nRF52840DK board prompts “J-Link V8.10c Firmware Restoration”.

[GUOQI123]

Hello expert.
My computer is windows11 system, using ncs+vscode for development, Jlink software version is V8.10c. My development board is nRF52840(PCA10056).
The problem I have now is that connecting to the computer via usb cable is recognized in vscode. As shown in the picture.
But you can't use it, you can't erase it, you can't flash it. And it will pop up this window "J-Link V8.10c Firmware Restoration." As shown in the picture.
I used Jlink's firmware burn tool to update the firmware, but the update was never successful.
I hope the experts can help.

Hello,

Can you try with different cable?
