Class 'PragmaRX\Tracker\Vendor\Laravel\ServiceProvider' not found

when I'm on running "php artisan vendor:publish"
I get this. I tried Everything the possible solutions but nothing works

I already added the provider in my app.php file.

[Symfony\Component\Debug\Exception\FatalThrowableError]
Class 'PragmaRX\Tracker\Vendor\Laravel\ServiceProvider' not found

Start by checking the Laravel service-provider registration in app.php and reproduce the failure with php artisan vendor:publish. Trace why PragmaRX\Tracker\Vendor\Laravel\ServiceProvider cannot be loaded; the issue is done when the command runs without the class-not-found error.
