i had the same problem on my new W11 PC, after getting no help from Airnav i searched on the net, and found out it had to do with the " memory integrity" ; you have to turn that off and W11 did recognize the drivers, everything working again.
you will get a warning in the Windows Safety that you're system is at risk, but until Airnav come's up with a decent working driver, you just have to ignore that
