I tell you that during the day I did the following:
PCIe ACS override: Multi-function
I removed bluetooth.conf file from path /boot/config/modprobe.d/
I created a new virtual machine with O.O Kali Linux and just passed the WiFi device which was marked for VFIO on boot
Everything works within Kali.

So far the solution seems to have been:
1. Changed USB port to UNRAID OS Bootable USB
2. have gone through the process of shutting down the physical machine and disconnecting it from power for 2-3 minutes
3. have booted the physical machine and run the Kali Linux virtual machine without running any other virtual machines that make use of the WiFi device
I'm guessing you also need to have Fastboot disabled in the BIOS of the physical machine. (In my case it was always disabled)
In the next few days I will rule out the need to move the UNRAID OS boot usb to another USB port.
I don't know if I missed something we did. but I think that would be the summary until I drop point number 1, God willing .
