Hi,
Does this issue also occur in other types of files?
I suggest you open it in safe mode running the following command: Press Win + R, type "winword /safe" in the blank box, press Enter. If it works fine in safe mode, please check the add-ins in your Word and disable them.
Click File > Options > Add-Ins on the left side of the dialog. Then click the drop-down arrow at the bottom of the dialog box and select "COM Add-Ins" from the list, then click the GO button. What comes up is a list of COM-Add Ins that are loaded and running.
