Laravel 8.x redirect()->intended() keeps changing to the wrong url

I am trying to create a way to confirm the password when executing a sensible action on a website using laravel.

I use a form to create the action, that uses a route to the sensible action, using a middleware to confirm the password. At the end of the confirmation it returns redirect()->intended() to redirect to the action the route was originally was supposed to if no password verification took place.

The problem here is that no matter what, redirect()->intended() is never the action I wanted to execute in the first place, it just redirects to the page where the first form is generated.

I use a form to execute said action.

<form method="post" action="/user//sensible_page/"  enctype="multipart/form-data">
        
    
    <button type="submit" id="sensible_button" class="col-auto align-self-end btn btn-danger">Click to go to sensible page</a>
</form>

Here are the routes I use

    Route::get('/confirm-password', function () {
        return view('auth.confirm-password');
    })->name('password.confirm');

    Route::post('/confirm-password'function () {
        if(! Hash::check($request->password, $request->user()->password)) {
            return back()->withErrors([
                'password' => ['The provided password does not match our records.']
            ]);
        }
        return redirect()->intended(); //<--- this redirect is the one causing problems
    })->name('password.confirm');


    Route::post('/user/{username}/sensible_action/', [UserController::class, 'sensible_action'])->middleware(['password.confirm']); 

Here is the view to enter the password

<form method="POST" action="" novalidate>
   
    <p>Please confirm your password before continuing</p>
    <input type="password" id="password" name="password" placeholder="Password">           
    <button type="submit">Confirm</button>
</form>

And here is the action to be executed

    public function sensible_action(Request $request, $username)
    {
       
        $user = User::where('username','=',$username)->first();   
        User::findOrFail($user->id);
        $user->sensible_info=false;
        $user->save();
        return redirect("/user/".$username);
    }

Thank you for reaching the end and taking your time to help me.
