Target Laravelista is not instantiable - php

Question

I'm trying to post a comment to my news post using the Laravelista\Comments but I got this error: Target [Laravelista\Comments\CommentControllerInterface] is not instantiable.
It was working just fine before, and I didn't change anything except the interface design. Not long after I couldn't post a comments anymore. This is the package I'm using https://github.com/laravelista/comments
Tried adding Laravelista\Comments\ServiceProvider::class, to the config\app.php but it didn't do any change.
Is there any solutions?

So on Laravel 9 there seems to be an issue getting with $this->middleware('auth'); in the constructor in the vendor CommentController. A workaround that is working for me is to basically create a custom controller and move the middleware('auth') to the actual routes instead.
extend the vendor CommentController
Copy the original constructor from there into your new comment controller but remove $this->middleware('auth');
Copy/paste the store, update, destroy, and reply functions from CommentService in the vendor folder into your new controller.
update the config (config\comments.php) to point to your new controller, example controller' => 'App\Http\Controllers\CustomCommentsController',
copy the routes from vendor into your routes file and chain the middleware('auth') to each route there.
Note: I have not tested this with guest commenting enable.
Controller:
<?php

use Illuminate\Http\Request;
use Laravelista\Comments\Comment;

{
public function __construct()
{
if (Config::get('comments.guest_commenting') == true) {
$this->middleware('auth')->except('store');
$this->middleware(ProtectAgainstSpam::class)->only('store');
} else {
// $this->middleware('auth');
}
}
public function store(Request $request)
{
// If guest commenting is turned off, authorize this action.
if (Config::get('comments.guest_commenting') == false) {

if (!Auth::check()) {

];
}

Validator::make($request->all(), array_merge($guest_rules ?? [], [
