Dear @Abby Braithwaite,
Good day. Thank you for posting your question in the Microsoft Q&A forum!
Regarding your issue, I understand that you're having a frustrating experience trying to open PowerPoints from the Canvas app on your iPad. Also, I have tested it on my end and cannot reproduce the same error. Hence, it does need some more confirmation under an overall test environment inside Canvas to further test if a similar issue can be reproduced.
Since you have tried reinstalling PowerPoint for iOS, but the problem persists. I think it may be that the latest Office for iOS apps have compatibility caused by specific conditions. In this case, I suggest you send feedback to Microsoft and report the issue to your tenant admin (or IT team) for further troubleshooting.
Send feedback in PowerPoint for iOS
In PowerPoint, click your profile picture in the top left> Help & Feedback> Tell Us What Can Be Better. You can provide your email address, describe the issue, and provide the screenshot of the error message via the feedback.
Contact Microsoft Support
If you're willing, we sincerely recommend you contact your Microsoft 365 administrator, follow steps in this article to create a support ticket with Online Support. The support team over there has higher permission than us, they can help check the situation on your side, involve more resource to collect logs and help you do troubleshoot. This would be a more efficient way in handling this case for you.
For reference: How do I find my Microsoft 365 admin?
Sorry for the inconvenience again. Your patience and understanding are highly appreciated. Hope you stay safe and healthy.
