Uncaught TypeError in includes/connect-plugins.php:155 using Elementor Pro 3.18.1 #16

Dear Connect Polylang for Elementor team,

Since updating to the latest Elementor Pro (Version 3.18.1) on our WordPress webpage we get the following crash from Connect Polylang for Elementor Version 2.4.3 (using Polylang Pro Version 3.5.3), which leads to the Elementor Pro side panel not loading properly. Below is the crash report (resulting in the Elementor Pro editing panel not loading.

I "hacked" connect-plugins.php by commenting line 155. This solved the problem, but I am not sure if I created other problems.

Thanks and kind regards,
Christian.
