Modal "Lost Password" Stuck Loading

Hi and thank you.

We installed this theme (Game Addict) for a client and the modal “Lost password” on submit gets stuck loading. (see attached screenshot)

All plugins have been disabled. Cache (client/server) disabled. No security plugins. Tested on multiple browsers/os.

The “Lost Password” via the WordPress login (/wp-login.php?action=lostpassword) works correctly, and email is sending properly. Only the Modal “Lost password” fails.

Any ideas? Please help. Thanks again.
