I've got the same issue with 2.4 Wifi. Tried with 23.05.2 and master to no avail. I get "Could not set interface wl0-ap0 flags (UP): I/O error" from hostapd in logs. Of course with factory settings.
I have two AX6S, both RB01, one is older (about 1y) and it is working fine, the other is recent (2w) and exhibits this issue. Everything else is working fine on both units.
I'm wondering if there is any change in the wifi chipset in the newer versions. Since you have both devices (older and newer), you can compare dmesg output on both devices to try to identify any hardware difference.
Another option is to install pciutils package and run lspci -v to check the output for mt7915e on both devices to try to spot any difference.
Ok, I think we are back to an old bug or something. I've also opened a new issue.

Sorry for asking over and over again, but the information is not coherent, or in my case does not work:
After flashing/sysupgrade OpenWrt and after a restart, the device is stuck on input at the bootloader, autoboot does not work, even after the commands below:
I have same behaviour. AX 160 mode iperf3 gets only ~550Mbit/s in 1thread, a bit more than ac 80. I can not reach 1Gbit with file transfer from wired lan to wifi, it stucks at 600-800Mbit even at several threads, but it always make 1Gbit from lan wired to lan wired even in 1 thread.
Openwrt says me tx to my client "2041.2 Mbit/s, 160 MHz, HE-MCS 10, HE-NSS 2, HE-GI 1", and sometimes 2400Mbit, but i cannot reach even half of this speed.
5GHz just works terrible. Even on AX80MHz. I've configured 2 separate WiFi networks - for 2.4GHz and 5GHz. 2.4GHz works good: quick connect, disconnects are rare. With 5GHz it's just the opposite. Sometimes it just disappears from networks list while 2.4 is still here. But I've just switched to AC80 mode and it seems to be OK so far. Will see.
What do you mean by "higher channels are not fully supported", is there any known problem with AX3200?
I have one in dumb AP mode running on channel 100 @80MHz with no major problems, uptime 44 days. It's DFS channel here in EU but there are a lot of other APs/routers on channels 36-48 (apartment complex). Not a single DFS event, no radars around Standard one minute delay at AP startup.
Only strange thing is one windows 10 PC one room away after standby/sleep connects to AX3200 with something like 30s to 1 min delay. Tested with two adapters: one AX MT7921 based and the other AC RTL 8812bu.
I was not able to determine if it is a DFS thing, some windows problem or something with the AP.
Still on 23.05.2, there's no rush to upgrade
But why not "pure" WPA3? Yesterday I've changed WPA3 to WPA2 as you advised and at the first sight it helped. At least connect is quick, ping losses are rare, and there were no disconnects even on AX160. But I had no enough time to test.
Just tried 80ac and 80ax. When i switch to 80 ax, openwrt shows "1134.2 Mbit/s, 80 MHz, HE-MCS 11, HE-NSS 2, HE-GI 1" to TX rate.
TX Iperf 1 thread drops from ~550 to to ~450Mbit/s and windows file transfer wired lan to wifi lan speed drops from 70-100Mbyte/s to 70-85Mbyte/s.
RX 100-115Mbyte/s at ax160 drops signofically to only 40-60Mbyte/s when i switch to ax80. My laptop lenovo P14s with WCN685x.
So 160ax mode works, and works better for me, but not full speed, and it is sad.
I use two ax6s, about 1yesar, works stable with OpenWrt. I use SQM, WG client, PPTP server.
I have 2.5Gbit wired lan and tried LACP for two ax6s lan ports from 2.5lan, iperf ax6s to ax6s gets 1.7-1.8Gbit in many threads, also ok.
Only one issue is wifi speed. It is never up to 1Gbit at TX file transfer, but iperf3 in many threads can reach TX 1.4Gbit sometimes.
