I saw your post from January and just ran into the same issue. Here's how I got around it:
Go to YAML and remove knit: pagedown::chrome_print.
This takes care of the dependency issue entirely, to the best of my understanding. It just means that after you knit your document, you'll need to print it manually. Small potatoes, in my view, because it this gives us access to pagedreport on RStudio.Cloud.
Hope that helps!
