A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
What changes did you make to your computer or subscription before the issue occurred?
I suggest running Online Repair to thoroughly fix the Office installation:
In the search bar, type Control Panel > Programs and Features > Microsoft 365/Office > Right-click > Change > Online Repair.
If the issue persists, open PowerPoint in Safe mode:
Press Win + R, type powerpnt /safe, and press Enter to start Microsoft PowerPoint in Safe Mode. This loads PowerPoint with only the essential components and temporarily disables add-ins, which can help identify if an add-in is causing the issue. If PowerPoint opens correctly in Safe Mode, go to File > Options > Add-ins and disable the add-ins one by one to identify the cause.
