Answer 1

update: upgrading from the laravel 5 way of declaring provide class in config/app, this ended up conflicting with laravel 6 package auto discovery, therefore causing even php artisan config:clear and composer dump-autoload not to work. removing 'Socialite' => Laravel\Socialite\Facades\Socialite::class in config/app.php solved this issue and re-installing the socialite package
