Cannot retrieve IMAP mail from Gmail using Thunderbird

My overall goal is to switch over from POP3 to IMAP without losing my previous messages. So I just created in Thunderbird an IMAP version of my POP3 Gmail account. I have been led to believe this is permitted and, clearly I don't want to wipe out my POP3 account (and all of its messages on my local system) until I know the IMAP works. So now I have two "accounts" defined in Thunderbird with the same email address: one is pointing to Gmail POP3 and one to Gmail IMAP. Now, any attempt to retrieve mail from IMAP results in the error "the mail server for account <xxxx>@gmail.com responded : Unknown command <gibberish string>". (See error image attached.) The gibberish string is different each time I try it.

I have enabled IMAP in my Gmail account config.

I have searched the web for similar problems and none of the proposed solutions work for me.

Other data: using latest Thunderbird on Windows 10. Any clues?

Looks like the image didn't make it into my question. I'll try again.

Your Gmail IMAP server settings look good. I'd also set the 'Authentication type' for the Gmail SMTP server to 'OAuth2'.

Try to start Windows in safe mode with networking enabled. - Win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode

Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/kb/safe-mode

Does the problem go away?
