Script fails to update after recent update to MAU and/or Office 365 apps

[damacguy]

When run as a script executed from Self Service msu-date runs through too quickly (movement in dock indicating activity) to actually be doing anything and nothing gets updated. But running msupdate manually from the command line shows updates available, and actually updates them.

Nothing has changed in my setup except new versions of O365 where it worked previously. Issue has also been reported on #microsoft_autoupdate on MacAdmins Slack group.
