Dear Trang Thien Truong,
Thanks for writing back and updating with us.
As per the further updates, the behavior you are encountering is not expected despite of using the latest version of the Word application.
In this situation, I am sorry to convey that the problem should be further investigated by the related development team, where they can collect the related logs while reproducing the problem and perform further investigation.
Note: I have checked the service health dashboard at the Microsoft end, where there is no related incident or issue reported.
So, I request you to connect with your IT admin of your organization (How do I find my Microsoft 365 admin? - Microsoft Support) and raise a new service request from the Microsoft 365 admin center so that the related development team will connect with you and investigate the issue further.
Reference: Get support - Microsoft 365 admin | Microsoft Learn
Note: We apologize for redirecting you to related development support team because the moderators in this community are limited with the resource for further investigation and to get a quick resolution to your problem, we requested it.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
