Workaround

Please, make sure of having a full backup of your site before proceeding.

• Open …/wp-content/plugins/sitepress-multilingual-cms/classes/ATE/Loader.php file.
• Replace:

  			Hooks::onAction( 'wp_loaded' )
  			     ->then( [ self::class, 'getData' ] )
  			     ->then( $maybeLoadStatusBarAndATEConsole )
  			     ->then( Resources::enqueueApp( 'ate-jobs-sync' ) )
  			     ->then( Fns::always( make( WPML_TM_Scripts_Factory::class ) ) )
  			     ->then( invoke( 'localize_script' )->with( 'wpml-ate-jobs-sync-ui' ) );
  

• With:

  		if (current_user_can('translate') || current_user_can('manage_options') || current_user_can('manage_translations')) {
  			Hooks::onAction( 'wp_loaded' )
  			     ->then( [ self::class, 'getData' ] )
  			     ->then( $maybeLoadStatusBarAndATEConsole )
  			     ->then( Resources::enqueueApp( 'ate-jobs-sync' ) )
  			     ->then( Fns::always( make( WPML_TM_Scripts_Factory::class ) ) )
  			     ->then( invoke( 'localize_script' )->with( 'wpml-ate-jobs-sync-ui' ) );
  		}
