Hi,
Since when did you start experiencing this crash issue? Have you made any changes recently to your computer?
Please try to launch Word 2013 in safe mode and see if issue persists. If it works well in safe mode, then it is due to add-ins:
Press Win + R and type "winword /safe" in the blank box, then press
Enter. (Please note there is a space between ‘WinWord’ and /. )
Please also check for updates and install any required ones, then check result. It’s always a good idea to keep current with updates.
Hope it helps and please feel free to post back with any findings.
Regards,
Ethan Hua

It's recommended to download and install
Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office
programs.
