Using both the latest version of Elementor and Quform.
I had an issue where conditional logic was not working with Quform and conditional logic inside of an Elementor Popup. Inspector showed no errors. Copied / pasted your JS above, and it fixed it immediately!
PS. I know sometimes other plugins can play a part in issues, If you wanna investigate the issue with an install I was having the issue on just let me know and I can give you login credentials to go in and tinker around.
