Unable to install pages put on marketplace

I have to make a new app because my last one was corrupted. Do I actually have to redo every single thing I did or is there a way to copy my work over? Every time I try to download a page I uploaded to the marketplace from the original app I get an alert “Unable to find all required dependencies”

Is there anything that can be done?

Hi, make sure that the new project has all required composite components and custom flows installed before attempting to copy the page from marketplace.
