Regarding this issue, I suggest let’s test this issue in Safe Mode.

Start the Office program in safe mode
==============
1. Click Start, point to All Programs, and then point to Microsoft Office.
2. Press and hold the CTRL key, and then click the Office program you want to start.

If the problem does not occur in the safe mode, this issue might be related to some third-party add-ins in the Office program, we can try to disable them. Normally, you could do the following to disable the conflict add-ins in your Office program:
Disable add-ins
***************************
a) Click File menu, click Options > Add-in, click Go button in the Manage: Com-in Add.
b) Check if there are any add-ins, clear the checkbox send to bluetooth
c) Close the Office program and restart it.
