Plugin Compatibility Issue with PHP 8.3

I wanted to report that the plugin is not fully compatible with PHP 8.3. Upon running it in a PHP 8.3 environment, the following warning is generated:

Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /var/www/csi/html/wp-includes/functions.php on line 7329

Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /var/www/csi/html/wp-includes/functions.php on line 2189

  420                  $sdk_symlink = $fs_active_plugins->plugins[ $this_sdk_relative_path ]->sdk_symlink;

  234               . '/start.php' );

  297           . '/'

  298:          . str_replace( "../{$themes_directory_name}/", '', $fs_active_plugins->newest->sdk_path )

  299           . '/start.php' );

admin\class-shortcodes-ultimate-admin-about.php:

  11        $this->add_submenu_page(

  12:           rtrim( $this->plugin_prefix, '-_' ),

  13            __( 'About', 'shortcodes-ultimate' ),

  15            $this->get_capability(),

  16:           rtrim( $this->plugin_prefix, '-_' ),

  17            array( $this, 'the_menu_page' )

admin\class-shortcodes-ultimate-admin-addons.php:

  24        $this->add_submenu_page(

  25:           rtrim( $this->plugin_prefix, '-_' ),

  26            __( 'Add-ons', 'shortcodes-ultimate' ),

This issue seems to be related to deprecated functionality or compatibility issues in theabove files. It would be great if the plugin developers could investigate and update the codebase to ensure compatibility with PHP 8.3.
