I suspect you have encountered https://github.com/e107inc/e107/issues/4938, which is actually a low-level PHP bug (https://github.com/php/php-src/issues/10200).

We have a workaround from https://github.com/e107inc/e107/commit/6b75f341ad54bdc8c7333acecd0ca435a07b2086. Try applying this patch to see if it resolves your issue:

diff --git a/e107_handlers/xml_class.php b/e107_handlers/xml_class.php
index 16adeb0f26..10a5d57f16 100644

        $ret = array();

-       $tags = get_object_vars($xml);
+       $tags = (array) $xml;

        //remove comments

I am forecasting that PHP 8.2.2 will fix https://github.com/php/php-src/issues/10200, so as an alternative, you could wait for that release.

PHP 8.1 is not affected, so that's yet another option.
