Could you try getting debug logs as generated by the qmi-proxy?
There's are some "broken pipe" errors in the MM log that I don't like,
maybe the proxy is segfaulting or something. Steps to get the logs
would be:

$ sudo systemctl stop ModemManager
$ sudo killall -9 qmi-proxy
$ sudo /usr/libexec/qmi-proxy --verbose --no-exit > /tmp/qmi-proxy.log 2>&1 &
$ sudo systemctl start ModemManager

Hopefull you'll then get the qmi proxy logs in that file, let's see if
we see something there.

Note the qmi-proxy binary may be in another path in your distribution.
