Thunderbird asks for Gmail password, but the 'next' button is broken

On my Windows 10 PC, I use Thunderbird (TB) for four emails (3 are Gmail). For some reason one (and only one) of my Gmail accounts starting wanting password verification in TB. But when I click the 'next' button, it doesn't take me to the password page to confirm my password, it just erases my Gmail account name in the username field.

I'm not certain why it suddenly started needing password verification (and my other two Gmail accounts still don't). I've logged into the Gmail account on Google, and my password still works (haven't changed it). I updated TB to the latest version. I deleted the password in TB (hoping it would then let me reenter it). I finally deleted the Gmail account entirely from TB. When I try to add it back, it now only allows the inbox (not sent or templates folders). And it still keeps asking me to verify the Gmail password (but won't let me). I can see new emails received, but I can't send any.

Any suggestions?

In TB Options/Privacy & Security, make sure Accept cookies is checked and 3rd-party is 'Always'. Confirm that the authentication for incoming and outgoing is OAuth2.

Thank you sfhowes, it worked!!! 3 days of frustration gone in 5 minutes! You're amazing!!

Not sure how the cookies thing became an issue now (and why it didn't affect my two other Gmail accounts), but glad it's over. A thousand times thank you!!!
