Did something happen to Trusted Location settings - new pc, Office update, new Windows version? New bitness from before (i.e. you moved from 32 to 64)? Not sure if that's pertinent or not, just suggesting recent change(s) might be the culprit. Maybe IT rolled modified a policy so that such scripts are now blocked.
See if you can run the cmd or bat file manually. If not possible, seems like a policy change.
The more we hear silence, the more we begin to think about our value in this universe.
