You've got 2 main problems with this code:

User::find($user)->update(['n_photo' => $photo_name]);

First of all, the correct syntax would be to use $user->id, not $user:

User::find($user->id)->update(['n_photo' => $photo_name]);

Second, that is super redundant; $user is already the result of User::find(), so you're doubling up for no reason.

To fix your issue, simply adjust your code to:

$user->update(['n_photo' => $photo_name]);

Just spacing issue please check these two lines

//Before // Wrong

$photo_upload     =  $request ->n_photo;

$photo_extension  =  $photo_upload -> getClientOriginalExtension();

//After //Correct

$photo_upload     =  $request->n_photo;

$photo_extension  =  $photo_upload->getClientOriginalExtension();

function user_update(Request $request){
           $photo_name = '';
           $user= User::findOrFail($request->id);

           if ($request->hasFile('n_photo')) {
               $photo_upload    =  $request->n_photo;
               $photo_extension = $photo_upload->getClientOriginalExtension();
               $photo_name      =  "toletx_auth_image_". $user . "." . $photo_extension
           Image::make($photo_upload)->resize(452,510)->save(base_path('public/uploads/auth/'.$photo_name),100);
           }
            $user->update([
