Thank you for the firmware update. With this firmware and the mt76.git 
commit 678071ef7029 ("mt76: mt7615: clear mcu error interrupt status on 
mt7663") + hostapd commit 14ab4a816c68 ("Reject ap_vendor_elements if
its length is odd") , I was able to connect to an 6GHz AP:

    $ cat > station_sae_test.conf << "EOF"

            proto=RSN
            ieee80211w=2
            beacon_int=100
    }
    EOF

    $ ip link set up dev wlp5s0
    $ ./wpa_supplicant -D nl80211 -i wlp6s0 -c ~/station_sae_test.cfg -B

    $ ping ff02::1%wlp5s0
    ....
     

Just as note: It is still not possible to see beacons when using the card in 
monitor mode.
