rtl8812au.ko never passes auth after Ubuntu 18.04 kernel upgrade (4.15.0-122-generic -> 4.15.0-123-generic)

[Braklet]

I've used this driver for years to enable a variety of USB interfaces. I'm now using a Netis WF2190 AC1200 dongle. It stopped working yesterday after a kernel upgrade.

The kernel builds w/o errors in DKMS and manually; the module loads, it enables the hardware and tries to connect to my preconfigured WLAN. However, it fails to authenticate:

Basically, an endless cycle of connect/start auth.

If anybody runs across this error, I was able to use the aircrack-ng driver with 4.15.0-123-generic:
