Termination Reason: Namespace CODESIGNING, Code 0x1

Removing the apps and reinstalling is likely to resolve this. What version of Office apps are installed on your computer? There was just an update to 16.11 yesterday. It's possible that the update didn't complete properly.
(This crash has nothing to do with your subscription status.)
