Duplicate of #14834. In short: PHP 8.1.x is not compatible with a libxml version higher than libxml2.12. This is because the libxml project made some breaking changes and we don't do bugfix releases anymore for PHP 8.1, so the compatibility was only fixed in PHP 8.2 and up.
In theory backporting 67259e4 should suffice.
