Please update Office to the latest version to check this issue.
If it doesn’t help, try to open Word in safe mode to eliminate interference from add-ins and startup items.
Open Word in safe mode: Press Win+R, type winword /safe, click OK.
Besides, are there any third party applications installed like Tuneup Utilities, Abby Finereader, Kaspersky Anti Virus etc.?
If there are, please close them one by one and see if the issue still occurs.
More information, methods in "Troubleshoot problems that occur when you start or use Word" may be helpful to you.
