Tested with simple webform "contact" example on "multi-lingual" site
Drupal composer built v. 8.6.3
Webform composer built v8.x-5.0-rc31

Displaying the submission on /admin/structure/webform/manage/contact/submission/1 throw the Exception
Exception: Object of type Drupal\Core\Language\Language cannot be printed. in Drupal\Core\Template\TwigExtension->escapeFilter() (line 465 of /web/core/lib/Drupal/Core/Template/TwigExtension.php).

On submission, the submission entry is auto-added with Drupal\Core\Language\Language

When I intercept the exception throwing of /web/core/lib/Drupal/Core/Template/TwigExtension.php on line 465 by...

465: var_export($args);exit;
466: throw new \Exception('Object of type ' . get_class($arg) . ' cannot be printed.');

It shows...

Language: Drupal\Core\Language\Language::__set_state(array( 'name' => 'Thai', 'id' => 'th', 'direction' => 'ltr', 'weight' => -10, 'locked' => false, ))

The submission line is shown in /admin/structure/webform/manage/contact/results/submissions as attached picture

    Modify the code as needed to correctly handle the Language object in twig file. Remember, you should access properties or methods of the Language object (like getId() for the language code) instead of trying to print the object directly.
    Error Code:- <span class="icpdlogo"><img src="{{ base_path ~ directory }}/images/icpd-30-logoinverted-{{ language }}.png" alt="ICPD"></span>
    Correct Code:- <span class="icpdlogo"><img src="{{ base_path ~ directory }}/images/icpd-30-logoinverted-{{ language.getId() }}.png" alt="ICPD"></span>

    Thank You!
