2] Check file format support

Although Word supports many file formats, it is recommended to use JPG, PNG, or BMP so that you can scale them according to your requirements. On the other hand, Word may often block you from adding a low-quality image due to scaling issues.
Therefore, you must ensure that your desired image is of good quality and is in the format mentioned above.

5] Check in Safe mode

At times, macros and add-ins could cause this problem. If so, first you must find out whether they are actually accountable for this problem or not. Then, you should find the problematic add-in or macro.
To get started, open Word in safe mode. For that, press Win+R to open the Run prompt, type winword /safe and hit the Enter button.
Alternatively, search for Word in the Taskbar search box, press and hold the CTRL key, and click on the search result.
Once it is opened, try adding the watermark with the same image. If you can insert the watermark, close the Word window and go to File > Options > Add-ins. Then, select COM Add-ins and click the Go button.
Remove the tick from all checkboxes and click the OK button.
If it resolves the issue, enable one add-in at a time to find out the culprit.
6] Repair Word installation

To repair the Word installation, you must repair either the Microsoft 365 or the entire Office installation. You can go through this guide to repair Microsoft 365.
