That is a diagnostic step, not a way to use Word. Do you have the same problem?
If it works fine in safe mode, that tells me that the problem resides in one of two spots:
· Your Normal template, or
· one or more Add-Ins (that you may not even know are there)
The Normal template is easiest to check.
1. With Word closed, find and rename your Normal.dotm template.
Where is the Normal Template / How to Find the Normal Template
2. Name it something like Normal2023.dotm.
3. Start Word and see if the problem persists.
4. If it does persist, then close Word, go back and rename your template back to Normal.dotm. Then you can...
Check for Problem Add-Ins (takes a bit more effort). Here is my page on this: Add-Ins in Microsoft Word
1. There are primarily two kinds of Addins to check. The COM Add-Ins and the Word Add-Ins. Here are the buttons on the Developer Tab.
2. You will want to disable them all by using the checkboxes. If some are already unchecked, make a note of that so you do not activate those ones later by mistake. You can do this with the COM Add-Ins first and then the Word Add-Ins.
3. Do not use the command-line switch because that also uses a fresh Normal template.
4. Then, one-by-one enable them and check for your error. When it pops back up, you have identified the culprit.
5. If all of them pass, check the store Add-Ins (the first button). I have not heard of problems with the Store Add-Ins but that may just show my ignorance.
Once you have identified a culprit Add-In you have to decide if it helps you enough to be worth this problem. Contact the developer of the Add-In and let them know about the problem. See if that developer can help.
