Windows 7 Home Thunderbird 115.13.0 (32-bit)

Today, this started showing up on one of my gmail accounts when I Get Messages: The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials.

Settings on all accounts: Server type: POP Mail Server Server Name: pop.gmail.com Port 995 Connection security: SSL/TLS Authentication method: OAuth2

I have several gmail accounts. I have one gmail account to which all the others forward. That account receives emails sent to the complaining account, and Thunderbird downloads the emails. So the problem is with trying to download from the (empty) complaining account. I can log in to the complaining account on line (via Firefox). So the password I use on line is OK.

No virus blocker.

Does anyone know what is going on?

Skipping many details, I finally removed all entries for the complaing account in Saved Passwords (Tools/Settings). The problem went away.
