What is the PCAP supposed to show?  There's no Connection attempt in there.

Anyway, I was curious and snooped on wpa_s from git trying to connect to an 
iPhone 12 Personal Hotspot (Maximum Compatibility option off, so it uses SAE). 
Not a pretty sight.  Firmware fails with errno=-52, Invalid exchange.  Has 
anyone from RPI team actually tested this firmware before pushing it out?

I also tried the old firmware with SAE_OFFLOAD bits, and that doesn't work with 
wpa_s or iwd either.

Until someone sends me a iwmon trace showing CMD_EXTERNAL_AUTH exchange working 
on an WPA3-Personal Only network, I remain skeptical that any of the Cypress 
firmwares actually work.
