We uncovered the same driver issue shortly after deploying 802.11ax. We mitigated by leaving 802.11ax enabled on the 5GHz radios, but disabling on the 2.4 radios. This way, compliant devices can connect and take advantage of 5Ghz connectivity. Those devices with faulty Intel drivers can still connect, albeit at substantially reduced data rates. There may be some inner workings of 802.11ax that I don't recall, but this worked for us!
This was on our Mist AP43s, limited to a single building. The rest of campus is running 802.11ac access points from Aerohive.
