Thx @IbrahimMD1 :-)
I had the same problem with another model, AX88772B, and your solution helped perfectly. Just a note to your step 9:
When /usr/sbin/spctl kext-consent list executed, no lists were returned since no lists existed. Hence I just added 5RHFAZ9D4P by running the /usr/sbin/spctl kext-consent add 5RHFAZ9D4P and then followed the rest of the guide.
And between step 13 and 14 a restart was needed as well.
Yet again, many thanks for this help.
