The 5.13.0-20 kernel works on this XPS 13 9310, but you may have to disable/ enable the device in BIOS (Connectivity -> WLAN and UEFI WiFi stack) before it appears again. Also possible that full power cycle does the job but haven't tried that yet. The exact sequence of steps required to reproduce this remains unknown to me but it looks like the failed attempt to load the device driver in the -21 kernel sends the system into a state that requires some BIOS activity.
