Hello, I hope you don't mind. This extension you've created is exactly what we need. Thank you.
However, after I installed it and tried to activate it, it prompted a crash.
My system:
wordpress:6.1.1
polylang:3.4.4
ultimate-member:2.6.8

crash log:

Fatal error: Uncaught Error: Call to a member function get_prop() on bool in /usr/local/lighthouse/softwares/wordpress/wp-content/plugins/um-polylang/includes/core/class-um-polylang.php:127

Hi @sanitpeng

This Fatal error occurs if Polylang returns bool instead of the PLL_Language object. I can not reproduce this issue, Polylang returns a valid PLL_Language object on my site. Please describe steps needed to reproduce this issue.
I changed the code to avoid a Fatal error. Please try a version from the branch development.

Thanks
