I actually think your problem is here:
https://github.com/htetzawphyo/Book-Shop/blob/main/resources/views/home/cartDetail.blade.php

and this onchange="autoSubmit()" in the form (one for each item). You see, you've declared it like:

function autoSubmit(){
            document.forms['submit'].submit();
        }   
        

which I guess submits always the first form in the document. You could've easily known this, if you've debugged it a bit more, just put some

dd($request->all())

on starting of the updateCart method in the controller, start clicking and it'll reveal what you need to know.
