@jpacis1 , unfortunately, I am not able to replicate what you've described; I downloaded the .imscc export package (for the entire course, not just the home page) and successfully uploaded it to a course using the instructions in How do I import a Canvas course export package? It took under a minute for the entire course to import successfully.
I've attached an additional .imscc package to the prompt, this one for the page itself.
Are you able to try this using a different device? If not, you will need to submit a ticket to Canvas Support or contact your school eLearning department to get additional assistance.
