Fatal error in L10n::get_main_lang_code()

Hello and thanks for that amazing plugin.

It works great in my local environment, but when I tried use it on a live environment (a shared hosting), I’m seeing the following error:

It looks like ResourceBundle::create() returns null in my case and there’s no check to handle that case.

I checked and the PHP Intl extension is installed on the webhost.

Any chance there’s a way to fix this? I can try to provide more information if needed.
