Custom Camera Rig Not Playing Animation

I am trying to play an animation with full camera animation in-game using a custom rig (see below)

However, when I load the animation I made into the game, it does not play. The R6 rig animation I also did plays though. Studio says both animations are playing (see below), but only one of them actually works.

The HumanoidRootPart is CanCollide false and Anchored true, and the other two parts are false for both. The animation works in my animator (moon animator) and also works when I import it into the default animation editor.

I have looked through many different devforum posts, and could not find a solution. This issue has been affecting me for a long time on multiple different projects.
