Also test in Safe Mode, follow these steps:

winword /safe
If word safe works as expected, 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 Word program:
1. Click File menu, click Options >
Add-ins, click Go button in the Manage:
COM Add-ins.
2. Check if there has any add-ins, clear the checkbox to disable them.
3. Close the Microsoft Word and restart it.
4. Add one check back each time to the list of Add-In, restart Microsoft Word, and repeat the above procedure. Once the issue reappears again, we can determine which add-in causes this problem and then disable it.
Best regards.
