Hi there, @JamesLarson ...
That doesn't sound like normal Canvas behavior. Have you tried reaching out to the Canvas Support folks to see if they might be able to help you troubleshoot this issue? That's what I would first recommend.
How do I get help with Canvas as an instructor?
Also, have you ensured that your browser is up-to-date? Generally speaking, Google Chrome and Mozilla Firefox are good options when navigating around the Canvas environment. You can run a browser check by visiting this page: What are the browser and computer requirements for Instructure products?.
Also, try clearing your browser history/cache. After you do that, close your browser, re-start the browser, and then log back in to Canvas. Try creating the new page again to see if you get the same error.

Hopefully you'll be able to get this resolved soon. Please keep us posted here in the Community so that we know how you were able to get things fixed...thanks!
