Did you try again to switch back to iwlwifi?
What happens if you are on a running iwm setup and then do the devctl
detach, set driver dance?
So on my current running iwm setup without changing anything else I did
the devtl detach, set driver dance which failed as follows:

You got an error here.
Was there anything else logged?

My next action could be to define both wlans_ entries in rc.conf and set
the devmatch_blocklist to if_iwm and reboot the laptop (without
rebuilding world and/or kernel) ?
I think we should first figure out why you get an error above.
If in hte current state you set the driver back to iwm, will that just
come back and work again?
