Maybe you could try with what RPiOS ships.

I get this with the default RPiOS verison of hostapd:
# hostapd -v
hostapd v2.10

IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
Copyright (c) 2002-2022, Jouni Malinen <j@xxxxx> and contributors
And also with the one I built from source. The latest hostapd I could find.
The git repo it is built from is from here: https://w1.fi/hostapd/
# hostapd -v

My hostapd.conf is:
# cat /etc/hostapd/hostapd.conf

If there is something wrong in my setup, let me know.
Hard to tell. The above looks okay, but no idea what your setup looks like.
when I start hostapd with dnsmasq, an interface comes up and I can
connect. As soon as it connects, it disconnects:

So does this mean you run with two wifi interfaces, ie. wlan0 and ap0? Can
you try with just only an AP interface?

So looks like connection and security are setup correctly...

So not clear what triggers these disassociated events. Can you enable debug
prints in brcmfmac, ie. use debug=0x100400? The levels are defined in
debug.h [1]

Assuming it is stopped manually here. Correct?
