Texture not displaying properly in any mode except Texture Paint

I am very new to blender so apologies if there’s an obvious solution I haven’t tried yet.

The two images I have attached are of my current project: attempting to turn my minecraft skin into a 3D model. I was using this tutorial (which is 3 years old and outdated but I’ve been using google to find how to do the things) https://www.youtube.com/watch?v=3VYWQgRvhQ4

The texture of my model is perfect in texture paint mode. Exactly how it should be. It’s messed up in every other mode though for some reason and I’m unable to figure out why. I’ve even looked at the texture itself and it’s fine, I’m not sure why it’s not displaying properly in almost every mode.

Please help.

EDIT:

Here’s the blender file of my project.
