Hello Amy Ricketts, welcome to the Microsoft Community.
I understand that you encountered an issue when copying from Word to PowerPoint. I would like to know when this issue started occurring. Confirming this might help identify the cause of the problem.
On the other hand, you can perform a simple test by:
- Copying from Word to Excel
- Copying from Excel to PowerPoint
Using Excel as an intermediary can help us determine whether the issue lies with Word or PowerPoint.
Additionally, repairing Office often resolves most issues, so I recommend you try this first: Repair an Office application - Microsoft Support
If a quick repair does not work, consider an online repair. This will re-download the Office applications and overwrite the currently installed applications to fix any potential errors. It takes longer, so I suggest trying it during your free time.
The following solutions are also worth trying:
Reset Office
Create a new local account
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
