I'm going to post here too as I have a similar issue with 2FA. Except for me, it tries to open a link, but nothing is associated with that link. I have Authy on my desktop, but it does not open that. Normally activating 2FA gives a QR code or a string of characters. You can manually input that string into whatever 2FA app you use, and it generates the 6 number return that you paste into the site to authenticate. But I only get the open as a link option.
I'm on Linux desktop using web browser.
