Yeah I am guessing that it worked but it froze, so your computer might no longer need to go through 2FA.

Yet another attempt

What happens if you click on Re-send the code?

Maybe too much attempts has been made without a success? Can you log-in on the Apple website, then delete the file in ~/.config/Sideloader/device.json and ~/.config/Sideloader/adi.pb? (and retry)
