Hi
I having a problem programming my nRF52840 Dongle from the Programmer v3.0.6 in nRF Connect for Desktop v4.0.0 (on Windows 10 @ AMD Ryzen 7). I put the dongle in dfu mode by pressing the reset button on the dongle and it starts pulsing the led red and the programmer is also able to find it (The device I can select is called Open DFU Bootloader / D1871BF59F6B). Selecting and open this device in the programmer it just tells it is an UNKNOWN_FAMILY and zebra stripes are shown. Turning on the verbose logging gives this output:

What can I do to solve this apparently access issue?
