Help Needed: Character Animation Not Working

I’m new to PlayCanvas and am having some trouble with character animations. Specifically, my character’s animations are not working as expected.

I’d really appreciate it if someone could guide me on how to properly set up and transition between these animations.

here is my editor if someone tell me how to play the walking animation in my charactors
