Disconnection Bug on Win 11 with Intel adapter

There appears to be a bug that causes the network adapter "Intel(R)
Wi-Fi 6E AX211 160MHz" on Windows 11 (with all current updates) to
disconnect and re-connect to the WiFi network a few times AFTER
disconnecting a WireGuard client profile. If the WireGuardTunnel
service can be either set to automatic startup or be started later
after Windows loads.  The WireGuard connection will remain stable and
connected until the WireGuardTunnel service is stopped, that is when
the connection issues begin, the Internet will be lost for about 20
seconds each time, sometimes more, then reconnects (and usually last
5-15 minutes while the adapter disconnects and reconnects to the
normal network). The issue could be lasting longer than that, I did
not have the patience after each test with reboot.

Have tried:
-Disabling windows firewall and windows defender
-Disable/enable the Intel network adapter quickly after disabling the
WireGuard tunnel service.
-Changing many of the adapter settings.

After each test, I rebooted.

It seems only a reboot solves the issue, and the intermittent
disconnection issue will start again after connecting/disconnecting
the WireGuard profile.

If the WireGuardTunnel service is kept to Disabled status and I never
try to connect to a WireGuard client config during the test, then the
disconnection issue does not happen.

In the Event Viewer logs, it shows this a few times, only during the
issue which seems related:
The description for Event ID 7021 from source Netwtw12 cannot be
found. Either the component that raises this event is not installed on
your local computer or the installation is corrupted. You can install
or repair the component on the local computer.

Tested using the WireGuard installer wireguard-amd64-0.5.3.msi. There
are no other security/networking products on the machine that could be
