Hi khawaja khalil,
Thanks for posting in the community. We are happy to help you.
According to your description, I would like to collect more information about the situation.
- To troubleshoot the situation, please try to set PowerPoint into Safe Mode, then test again. Check if the situation still happens or not.
Close PowerPoint first, press win + R, in the Run box, type powerpnt /safe, and click OK.
- Could you please record a video about your steps and the situation? It will help us to test on our side.
You can use any 3rd party app or use PowerPoint (click the Recording tab> Screen Recording) to record the video. After that, please upload it to any online drive, like OneDrive, then share the file link with us.
- Please provide your Office version and product information. It will help us to test the same version on our side. You can click File> Account, please take a full screenshot of the current interface.
We look forward to your response. Thanks for your cooperation.
Sincerely,
George | Microsoft Community Moderator
