I'm facing somewhat similar.
I posted about my experience here: https://itch.io/t/4380853/images-from-page-game-are-not-showing
At least it's good to know I'm not the only one! What's weird is that other user's images show up again when they go to edit the page, but mine are still broken/missing on the edit page.
Hopefully it'll be addressed shortly. I wouldn't be surprised if some backend shenanigans that had to happen because of the Funko take-down attempt nonsense might be causing the CDN to act strangely...
