Replace this function

private function resetTranslationAvailabilityInformation() {
		global $wp_textdomain_registry;

		if ( $wp_textdomain_registry ) {
			$wp_textdomain_registry->reset();
		} elseif ( function_exists( '_get_path_to_translation' ) ) {
			_get_path_to_translation( null, true );
		}
	}

With this

private function resetTranslationAvailabilityInformation() {
		global $wp_textdomain_registry;
		if ( ! isset( $wp_textdomain_registry ) && function_exists( '_get_path_to_translation' ) ) {
			_get_path_to_translation( null, true );
		}
	}
