The only way to link the 2626 on Windows 10 / 11 for me too, is a hard boot. That means hot plugging the device a second time also doesn't work. If the 2626 somehow get's plugged out, a shutdown is required to ever get it working (blue light / sync) again. I have tried to change bios settings (ROG STRIX Z590-I) to solve this issue, without any luck.
Other than that, and the inconvenient power button, the 2626 interface is stunning!
