EXPLATION BY CHATGPT :

warning: Tried to instantiate Entity before Ursina. Please create an instance of Ursina first (app = Ursina()):

This indicates that you're trying to create an Entity object before initializing the Ursina application instance. Ursina requires that you first create an instance of Ursina using app = Ursina() before creating other entities. Ensure that your code follows this order.
no audio found with name: ...:

This warning suggests that the audio files referenced in your project are not found at the specified paths. Ensure that the audio files (clicking.ogg, subtle.ogg, uplifting.ogg) are correctly placed in the ringtones folder and that the paths in your code are correct.
Exception: Error in Mesh. Ensure Mesh is valid and the inputs have same length:

This is a critical error indicating that there’s an issue with the mesh data being loaded. Specifically, the error message details a mismatch between the number of vertices, triangles, normals, colors, and UVs:

Vertices: 8724
Triangles: 0
Normals: 8724
Colors: 8548
UVs: 8724
This means that the mesh data being loaded has inconsistent lengths for these attributes. For a mesh to be valid, all attributes (vertices, triangles, normals, colors, UVs) must have compatible lengths. If they don’t, the mesh cannot be properly constructed.
