Hi @Eaven HUANG ,
Did the Office 2019 using the same bit version with Office 2016 and Office 365? 32-bit or 64-bit?
Did you use custom font or the standard font?
I suggest you try to run Word 2019 as an administrator and check the result.
If anything is unclear with the previous information I've provided to you, please don't hesitate to let me know. I am glad to be of assistance.
