That was fixed some months ago in the following commit:

commit 28869463a1f93d980c72ae4e8c7997c9be899535

    iface-modem: allow Command() while in Failed state

    Allow the generic command API while in FAILED state, in case the modem
    integrator has some special commands to recover the device.

    Fixes https://gitlab.freedesktop.org/mobile-broadband/ModemManager/issues/163

The commit was not included in any stable release yet, I've just
cherry-picked it to the mm-1-12 branch and so it will be available in
1.12.10.
