This is bad, it couldn't load any of the HW information.

Not with the SIM card; not yet. Looks like the TTY replied only to AT
probing and failed to reply to the remaining commands we sent to e.g.
query manufacturer or model; all that is before the SIM card can be
used.

You'll need to run ModemManager daemon manually with --debug and grab
all the debug logs while you reproduce the issue, see:
