In the logs you see "Frame didn't validate as MMPDU". This means there 
was a malformed packet, or at least IWD thinks it was malformed. Could 
you get an iwmon capture while IWD is running and you attempt to connect 
with a client device? Also, have you tried connecting with several 
client devices (laptop, phone, etc)? That would tell us if its a 
specific client sending a bad frame, or a bug processing the frame. More 
info on how to do that here:

https://iwd.wiki.kernel.org/debugging

Note the capture will contain your devices MAC/SSID/PSK so if your 
worried about privacy you can send it just to me, or use a dummy 
passphrase just for the test, up to you.

Just a side note here, for a dual band access point you will actually 
need two separate adapters.
