Why can't I move Apple's own apps, like Safari or Pages?
Short answer: Built-in Apple apps are in a protected, read-only part of macOS, and other Apple-signed apps are updated in place by macOS or the App Store — so Storage Studio blocks moving them.
Apple's built-in apps live in a protected, read-only part of macOS, so nothing can move them. Other Apple-signed apps in your Applications folder are updated by macOS or the Mac App Store at their original location, which would undo a move — so Storage Studio marks them Blocked rather than risk a broken app.
If you need space, look at large third-party apps instead, or remove Apple apps you never use with Uninstall where macOS allows it.
