Fatal Error upon visiting plugin settings

Hi Gijo,

Upon activating the plugin and going to its settings, I am seeing the following message:

There has been a critical error on this website. Please check your site admin email inbox for instructions.

Below is the error log as reported by WordPress:

Fatal error: Uncaught TypeError: implode(): Argument #2 ($array) must be of type ?array, bool given in /home/user/example.com/public/wp-content/plugins/flying-scripts/settings/settings.php:19 Stack trace: #0 /home/user/example.com/public/wp-content/plugins/flying-scripts/settings/settings.php(19): implode() #1 /home/user/example.com/public/wp-content/plugins/flying-scripts/settings/view.php(27): flying_scripts_view_settings() #2 /home/user/example.com/public/wp-content/plugins/flying-scripts/settings/index.php(18): include('...') #3 /home/user/example.com/public/wp-includes/class-wp-hook.php(308): flying_scripts_view_view() #4 /home/user/example.com/public/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #5 /home/user/example.com/public/wp-includes/plugin.php(517): WP_Hook->do_action() #6 /home/user/example.com/public/wp-admin/admin.php(259): do_action() #7 /home/user/example.com/public/wp-admin/options-general.php(10): require_once('...') #8 {main} thrown in /home/user/example.com/public/wp-content/plugins/flying-scripts/settings/settings.php on line 19

Could you please help resolve the problem?
