Latest driver for Intel Wireless-AC 9560 no longer connects to company wifi

[Teaweasel]

I am an IT Administrator, and we are having issues connecting to our internal company wifi with any of the drivers newer than version 21.10.1.2. We can connect to other wifi networks, but our internal immediately shows "Can't Connect". We require a certificate to connect. Everyone with the issue has the correct certificate installed on thier machine, and has no issues connecting when the driver is uninstalled and reinstalled with the 21.10.1.2 version of the driver.

Everything looks ok, and nothing has changed in our network.

I installed and ran Wireshark....packets are not even sent. Wireshark is blank. I suspect it is internal, possibly with the driver?

Any suggestions on how to fix this? We have people working from home, but they need to come into the office sometimes and need to be able to use the internal company wifi in order to complete thier work. It is work they can't do on a wired connection or on a different wifi network.

Thanks
