Unable to view activation code to sign in

Every time I select Sign-In on youtube the small window with the init code is briefly displayed, but then it's immediately covered by the youtube settings window. There isn't enough time to see the code, thus I'm unable to sign in. This has been a problem for some time. This is the same whether I use the latest youtube plugin from the Kodi repo, or the latest git release. I've tried different skins and it's exactly the same. It's also the same on a new Kodi install, as well as one with several addons added. I'm currently using Kodi 18.1 Leia, with Youtube plugin version 6.4.0.

A brief error message is displayed (extracted from the log):

ERROR: [plugin.video.youtube] Requesting access token: Code: |400| JSON: |{u'error_description': u'Credentials in post body and basic Authorization header do not match', u'error': u'invalid_request'}|

ERROR: [plugin.video.youtube] LoginException: [400] invalid_request: Credentials in post body and basic Authorization header do not match

I'm using fully updated Arch Linux, running under Plasma 5.

Here's an updated, clean debug log: https://paste.kodi.tv/aworukijuy.kodi.

If I click on any other youtube link (eg Popular Right Now), I get a popup saying "Youtube: forbidden".

I've searched this forum, as well as the previous one, and have done a Google search without finding anything. I'd be grateful for any help. TIA.
