Error with Polylang plugin

After installing the Polylang plugin

I am encountering a fatal error on Arabic pages: PHP Fatal error: Uncaught Error: Call to undefined function formula_generate_css() in /home/mysti/public_html/wp-content/themes/formula/theme-menu/classes/class-formula-non-latin-languages.php:117.

This issue arises when creating or viewing Arabic pages after installing a multilingual plugin.

I have traced the formula_generate_css() function to the parent theme’s /assets/css/custom-css.php file, which is included in the parent theme’s functions.php.

I found that /theme-menu/menu-file.php (which loads the problematic class) seems to be included in functions.php before /assets/css/custom-css.php. You even tried reordering these lines in the parent theme’s functions.php, but the error persisted.

I also tried to force-load custom-css.php early in the child theme’s functions.php, but this didn’t resolve the issue either.

<?php

/**

• Force load parent theme’s custom-css.php very early.
  */
  function my_child_force_load_custom_css() {
  require_once get_template_directory() . ‘/assets/css/custom-css.php’;
  }
  add_action( ‘after_setup_theme’, ‘my_child_force_load_custom_css’, 1 );

/**

• Now load the parent theme’s menu file (which includes the problematic class).
  */
  function my_child_load_menu_file() {
  require_once get_template_directory() . ‘/theme-menu/menu-file.php’;
  }
  add_action( ‘after_setup_theme’, ‘my_child_load_menu_file’, 11 ); // Ensure this runs after our forced load
  
  So I need your guidance on properly resolving this conflict within their theme, ensuring compatibility with multilingual setups.

BTW, I am using elementor plugin to build my site
