It has matching PCI IDs so will be auto-loaded as well.
LinuxKPI has a lower priority though so the native iwm(4) will
preferably attach if available.

lagg is one of these configurations which still only work in very few
circumstances. One of the problems being show below the others being
outside of wireless but triggering the problem there.

It tried to attach but failed. Twice. Likely iwm(4) is already attached during these times?

Are you sure you had fully restored the previous rc.conf?
It seems you either had left the blocklist line or forgot to change the
wlans_iwlwifi0="wlan0"
back to iwm0 or maybe mistyped it?

Is that what the above messages show? These multiple attempts?

That indeed is a good question. Especially if there was a reboot/cold
start in between. My best guess is up there.

Okay.
Given your follow-up email. What's the state been since? Did you have
any further attempts at removing the loader lines for iwm again?
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?
In theory you should be able to leave both:
wlans_iwm0="wlan0"
wlans_iwlwifi0="wlan0"
lines in rc.conf so switching between one and the other is easier using
the devmatch_blocklist for iwm or doing it manually using devctl.
I assume you did etcupdate or mergemaster after an update to stable/13
so that this statement lists both iwlwifi and iwm:
set wifi-driver-regex
"(ath|bwi|bwn|ipw|iwlwifi|iwi|iwm|iwn|malo|mwl|otus|ral|rsu|rtw|rtwn|rum|\
run|uath|upgt|ural|urtw|wpi|wtap|zyd)[0-9]+";
Because then switching with devctl above should in theory auto-create
the wlan0 with the other driver again (if both wlans_*=".." lines are in
rc.conf).
HTH and still happy to hear more about this in the hope we can lift some
of the confusing weirdness that happened.
Lots of peace,
Bjoern
