Controller or its method is not found

I’ve recently upgraded CodeIgniter from v4.3.8 to v4.4.0 and encountered an issue with routing.
My controller is located at app/Controllers/Member/Dashboard.php and is set up for auto-routing.

However, when I attempt to access the URL http://localhost:8080/member/dashboard, I receive the following error:

Code:

Controller or its method is not found: \App\ControllersMember\Dashboard::index

I’ve verified with

Code:

php spark routes

that the URL route is indeed defined.

Could someone guide me on how to resolve this?
