It seems like Polylang no longer defines a PLL_PREFIX constant causing a PHP warning
Use of undefined constant PLL_PREFIX - assumed 'PLL_PREFIX' (this will throw an Error in a future version of PHP)
wp-content/plugins/polylang-supertext/src/Supertext/Polylang/Core.php:154
Thanks for the hint.
We built a new version of our plugin that is compatible with Polylang and WPML. But it's not 100% ready yet. Will make sure it's fixed there.

Current workaround: Add
define( 'PLL_PREFIX', 'pll_' );
