This issue has been seen as far back as macOS 10.13 High Sierra but persists for some users even after the upgrade to macOS 10.15 Catalina. One of the major known issues is that Keynote crashes in the middle of a presentation.

If your Keynote app shows you an error message saying it wasn't able to connect to iCloud when you opened a particular document, you can try dismissing the error message, closing the document and reopening it.
