(stopped here because it redirects to the free unauthenticated trailer)
(also replaced my 2FA code with 'PRIVATE')

Description of your issue, suggested solution and other information

Cannot authenticate to YouTube with 2FA enabled.

WARNING: Unable to submit TFA code: HTTP Error 500: Internal Server Error

Also tried old app-password method (would be preferred for easily retractable passwords in batch files), but since the code is updated to support 2FA, app passwords no longer work. Therefore, it is currently impossible to log into YouTube at the moment.

Post the output with --dump-pages.

Here is the info you requested with --dump-pages.
I still get the error, --dump-pages dumped a lot of gibberish (base64?), so had to pipe the output to files.

I noticed you ran the python raw, and your python version is newer than what you use to generate the Windows EXE, so I tried installing Python 3.6.4 (as you used), and even Python 3.7. I also noticed you used netrc, so I tried to replicate that setup as well.

This is from a git clone from today:

The only remaining differences that I cannot check against is the fact your Windows 10 build is very old. (10.0.10240 vs 10.0.14393), and our ffmpeg versions are different, but neither of these should matter, should it?

Edit: Noticed you had some extra EXE (phantomjs, rtmpdump), so also installed those. Updated the log. Still no luck.
