  Can you share shots of the character's root Inspector, and their Animator's Base layer?

  If your character's Animation engine is set to Sprites Unity, then the expected animations (listed if you click List expected animations?), will need to be present in the Base layer. If you switch to Sprites Unity Complex, then animations are driven using Animator parameters, which does support sub-layers.

  It became a little too complicated. The player character prefab has child objects of different sprites and different animations. By "layers" I meant them.

  But since the root player has only one selection of animation controller, and the 3 child objects shift visible/invisible, I think when they become invisible, that's when I get the warnings for not playing the animation.

  Up to ver 1.82.1, it worked flawlessly, without errors. But after 1.82.2 (and 1.82.3), things didn't go well no matter what I tried.

  So I reverted back to 1.82.1, and am planning to do no more AC updates for my project just for the sake of the player anims.

  The warnings appearance is based purely on the presence of the states within the Animator - the state of the GameObject children that they in turn affect should have no bearing.

  I'm sure this can be sorted out, but I would need to see the images / details mentioned above to know the situation in enough detail.

  Okay, below are the screenshots:

  Below is the code in my player character's script, attached as a component. It makes the child sprites visible or invisible:

  using UnityEngine;
  using AC; // Adventure Creator namespace
  
  public class DisableNubiaFrontAndBack : MonoBehaviour
  {
      private GameObject nubiaFront;      // Reference to the NubiaFront GameObject
      private GameObject nubiaBack;       // Reference to the NubiaBack GameObject
      private GameObject nubiaBackIdle;  // Reference to the NubiaBackIdle GameObject
      private Player player;
  
      public float facingUpThreshold = 0.8f; // The threshold for facing upwards (between 0 and 1)
  
      void Start()
      {
          // Locate the NubiaFront, NubiaBack, and NubiaBackIdle child objects
          nubiaFront = transform.Find("NubiaFront")?.gameObject;
          nubiaBack = transform.Find("NubiaBack")?.gameObject;
          nubiaBackIdle = transform.Find("NubiaBackIdle")?.gameObject;
  
          if (nubiaFront == null)
          {
              Debug.LogError("Child object 'NubiaFront' not found on the Player prefab!");
          }
  
          if (nubiaBack == null)
          {
              Debug.LogError("Child object 'NubiaBack' not found on the Player prefab!");
          }
  
          if (nubiaBackIdle == null)
          {
              Debug.LogError("Child object 'NubiaBackIdle' not found on the Player prefab!");
          }
  
          // Get the Player component
          player = GetComponent<Player>();
          if (player == null)
          {
              Debug.LogError("Player component not found on the prefab!");
          }
      }
  
      void Update()
      {
          if (nubiaFront == null || nubiaBack == null || nubiaBackIdle == null || player == null) return;
  
          // Check if the player is moving by evaluating their velocity using linearVelocity
          bool isMoving = player.GetComponent<Rigidbody2D>().linearVelocity.magnitude > 0.1f;
  
          // Get the movement direction as a Vector3 (this will depend on the player's movement system)
          Vector3 moveDirection = player.GetMoveDirection();
  
          // Check if the player is facing upwards (allowing for a broader angle)
          bool isFacingUp = Vector3.Dot(moveDirection, Vector3.up) > facingUpThreshold;
  
          // When the player is facing upwards (moving upward)
          if (isFacingUp)
          {
              // Hide NubiaFront
              SetGameObjectVisibility(nubiaFront, false);
  
              if (isMoving)
              {
                  // Show NubiaBack and hide NubiaBackIdle when moving up
                  SetGameObjectVisibility(nubiaBack, true);
                  SetGameObjectVisibility(nubiaBackIdle, false);
              }
              else
              {
                  // Show NubiaBackIdle when not moving up (idle state)
                  SetGameObjectVisibility(nubiaBack, false);
                  SetGameObjectVisibility(nubiaBackIdle, true);
              }
          }
          else
          {
              // When not facing upwards (player is not moving up)
              SetGameObjectVisibility(nubiaFront, true);
              SetGameObjectVisibility(nubiaBack, false);
              SetGameObjectVisibility(nubiaBackIdle, false);
          }
      }
  
      // Function to set the visibility of a GameObject
      private void SetGameObjectVisibility(GameObject obj, bool isVisible)
      {
          // Set the active state of the GameObject
          if (obj != null)
          {
              obj.SetActive(isVisible);
          }
      }
  }

  Your images are cropped - is the Animator on the sprite-child, and is the Animator showing the base layer?

  Do the "Cannot play animations" warnings go away if you disable your custom script?

  Your script disables the sprite child, which will prevent animations from playing. Your Animator will need to be on a shared parent for it to be able to affect the sprites on your separate Front/Back/Right objects, and the sprite child should always be kept enabled.

  Create a new Empty child GameObject, make it a child of the root, set it as the sprite child, and move your Animator there. If you then update your animations to have them reference the child GameObjects, you can also embed their enabled states within the animations - no need for a custom script.

  Yes, the animator is showing the base layer only. There is (was until now) only one layer in each animator.

  My problem is that I couldn't find a way to use multiple sprites (My 2D player character from the front/back) in a single animator.

  Here is how it looks now:

  I found a work around. Instead of toggling the PSBs visible/invisible, I made their scales switch between the world size/ zero. Now the warnings are gone.
