Hi, bailey_wm_f.
I'm sorry about that. Many users are reporting powerpoint issues after upgrading to Windows 11.
I suggest you send feedback to the Powerpoint team reporting this issue, Microsoft engineers can resolve this directly.
The simplest way is through the app itself:
In PowerPoint, click → Help → Feedback.
Choose the option <I don't like something> or <I like something> and explain the situation in detail.
Comments go directly to the product teams and are read daily.
