Adobe Opens PDFs Displaying only a Gray screen

I’ve downloaded the latest version of Adobe Acrobat on my Mac (running Sequoia 15.5). When I log in and attempt to open certain PDF files, they display as a gray screen.

These same PDFs open correctly in Preview, so the files themselves are not corrupted. I’ve also tested using a different Adobe account and encountered the same issue. This doesn’t appear to be related to macOS Sequoia, as I experienced the same problem on my previous operating system.

Interestingly, some PDFs—typically ones from businesses—open without issue. And some display partial gray areas. However, any PDFs I’ve scanned myself consistently fail to load and show only a gray screen.
