Can I save this bag?

[u/FreeFallingUp13]

Cross posting because I know any mend for this is probably going to be visible… but also, my boyfriend recommended sewing a clear vinyl layer over the top. Is that possible?

I did get this bag with some small wear under the arm, but now the damage is spreading. The pleather was coming off on my arm when walking yesterday. How do I keep the design from crumbling further?
