• If Word keeps crashing, it's possible that an add-in is to blame. If an add-in is causing the problem, start your application in safe mode by using the CTRL key while clicking on it. Don't let go of the CTRL key until it prompts you to confirm Safe mode.
• Start the application normally and disable add-ins one by one if you see them. After disabling each add-in, you should restart the application to see if it helps. Click the File tab, then Options, and then Add-ins on the left to access the add-ins. COM Add-ins can be found under the Manage drop-down menu. 
• If any add-ins are checked in the list, click Go and uncheck them. An add-in will be disabled as a result of this.
