By removing force_xmlsettings_for_survey_rendering configuration, I got a similar error. That's because confinguration is an object.



Twig\Sandbox\SecurityNotAllowedMethodError

Calling "tostring" method on a "TemplateConfiguration" object is not allowed in "string_template__b85a9d86339e4b676595fbe968ac295f" at line 234.

To debug like this, i usually do var_export($var, true); https://www.php.net/manual/en/function.var-export.php
Maybe dump() function can ignore __toString() special method and use the var_export() function?
Also print_r($var, true); has the same behaviour https://www.php.net/manual/en/function.print-r.php
