OK guys, please let me know if there are anything else you need me to do to
help you diagnose this.

All I can say is that if I am on wired OR on a Wifi that is not Wifi 6, I
do not see the freeze. But on my Wifi 6 access point it is easily
replicable.

That does not affect other OSes I have at home. Windows, Mac and Android
are all OK, so I know the base itself is not the problem.
