iwd 2.22 scan fails but... works ok with ConnMan

[Piotr Oniszczuk <piotr.oniszczuk@gmail.com>]

Hi,

I’m using iwd 2.22 as default way of automated wifi connection in my project (https://github.com/warpme/minimyth2)

Some of my users started to report issues about not able to establish wifi connections.
I asked to do 1st step verification: launch ConnMan (https://wiki.archlinux.org/title/ConnMan) to verify is HW working ok.

With ConnMan users are able to connect so HW is OK.
It looks to me like issue is specific to iwd.

With iwd log says like below.

May somebody from iwd team help me to solve this issue?
