Questions:
Is Twig being used in my site?
Can you assist with the transition if Twig is being used?
If you added the language switcher through WPML settings, a shortcode, or a widget, there is no need to worry; it will continue to function correctly.
However, if the switcher is implemented directly in your theme's code, you may want to consult the theme author to understand how the WPML language switcher is integrated. Alternatively, if you have the necessary skills, you can check the theme's template files yourself to identify the file responsible for rendering the switcher and verify how it has been integrated. Inspecting with the tool in the browser won’t indicate whether a Twig template has been used.
One important thing you can do is make sure that you have a full website backup for any of your sites, just to be safe in case something breaks. But not many people reported using Twig.
I hope that you will find this information helpful.

However, you can find a few examples and explanations in the following URLs:
