Rufus Portable Is Grayed Out

I downloaded portable Rufus but when I go to use it the functions are grayed out and the Media Creation Tool I downloaded does not appear in the App. My laptop is an Acer Aspire E15 and my OS is Windows 10 Lite by Phoenix. I am trying to put Windows 10 22H2 back on my PC instead of the Phoenix App, but I cannot make the bootable USB with Rufus. Any ideas? Thanks.
