Glitchy Model - z fighting or some other error?

I have a model for the main character for my game, and it’s appearing super glitchy whenever I play my game in-editor. Here’s a recording:

Why would the model be acting so strangely? What could I do to fix this?

I’ve found the solution to this issue: I was using a Vector2 to manipulate the scale of this 3D object (that’s what I get for re-using code). I’ve changed all my variables to Vector3s now, which has solved my issue.
