TP-Link BE65 and VHT/160

Hi,

I just replaced my AmpliFi devices with a (pair of) TP-Link BE65 and 
realised I'm unable to get more than 802.11a/54Mbps unless I set the 
channel width on the BE65 to 80. If left at the default 160, I can't 
connect (and I even observe firmware crashes on the iwlwifi).

Is this expected? I had kinda hoped I could let the others in the 
household enjoy vht/160 even if I can't (yet), so this is a bit puzzling 
to me.

I can provide debug info if useful, just tell me what you need. This is 
my Framework 13", intel 13th gen or something like that (not the latest 
Ultra).

Some info below - currently connected with vht80 and getting >300Mbit/s.
