Codeigniter 4 hosting problem

I'm uploading for my codeigniter project, I'm using codeigniter version 4, and I'm also using the myth/auth library, when I run the program on localhost there's no problem and it runs normally, but after hosting I get an error message like this CodeIgniter\View\ Exceptions\ViewException
Invalid file: App\Views\Auth\login.php
even though I have confirmed that the file exists, and for the base URL and path configuration I have also confirmed that it is correct. then I tried to move app>views>auth to myth's views folder which is in a vendor. and it works, the login page can load properly, but still can't log in, even though the database is also installed properly on my hosting.
