Could you please check the version of your Office?
Please try to update your Office to have a check.
Besides, I suggest you open Word in safe mode (Enter winword /safe
in Run dialog.) and create a new document to check this issue again.
If the issue still occurs, you can search "Event Viewer" > Windows Logs > Application, check whether there is any error of Word crash issue.
If yes, you can check the error module.
Any updates, welcome to post back.
