Failing to connect to AP (AP appears to change mode)

This happens on specific APs with advertising VHT I believe. The symptom is the wifi continuously disconnects and attemts to re-connect indefinitely.

Hardware is Framework 13 AMD Edititon https://wiki.archlinux.org/title/Framework_Laptop_13

WIFI/Bluetooth: RZ616 / MediaTek MT7922     PCI ID: 14c3:0616

Linux bagnaram-pc 6.11.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 04 Oct 2024 21:51:11 +0000 x86_64 GNU/Linux

This is the dump of the relevant journald:

Oct 10 09:22:27 bagnaram-pc kernel: wlan0: AP appears to change mode (expected VHT, found HT), disconnect
Oct 10 09:22:27 bagnaram-pc kernel: wlan0: VHT information is missing, disabling VHT
Oct 10 09:22:27 bagnaram-pc systemd-networkd[688]: wlan0: Connected WiFi access point: <RANDOM_AP_NAME> >
Oct 10 09:22:27 bagnaram-pc kernel: wlan0: associated
Oct 10 09:22:27 bagnaram-pc kernel: wlan0: RX AssocResp from <MAC> (capab=0x1511 status=0 aid=10)
Oct 10 09:22:26 bagnaram-pc kernel: wlan0: associate with <MAC> (try 1/3)
Oct 10 09:22:26 bagnaram-pc kernel: wlan0: associating to AP <MAC> with corrupt beacon
Oct 10 09:22:26 bagnaram-pc kernel: wlan0: authenticated

I have tried setting the the following flag that I believe to have an effect on the VHT but there was no effect.

[root@bagnaram-pc ~]# cat /etc/modprobe.d/mac80211.conf 
options mac80211 minstrel_vht_only=false

Things I know:
- I can connect to most access points. This one in particular is problematic and I accept that there are other ones out there with this issue too.
- I am in the same room as the access point so I don't believe collisions are an issue
