@YouTube Why can't I log in to my account? My issue isn't listed in the help center when I clicked troubleshoot. It tells me there was an issue logging in to my account, but I can log in just fine in an incognito window and in Safari. I rebooted the browser and reopened the tab.
Hmm, is this happening across devices? If you haven't already, try clearing the cache and cookies and let us know if that makes a difference. Keep us posted!
