I was having this problem trying to add a mail (not gmail) account just for Notes. In my ~/Library/Keychains folder, I found a subfolder with a long hexadecimal and hyphens name. I deleted that subfolder, logged out, and logged back in. I was then able to add the account, without having lost any passwords from my keychains.
If you get a corrupted message...
Naw, not damaged, it's just that you have an old copy already in Applications, there are 2 cures...
Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS High Sierra App in Applications, so expired Certificates are not expired.
Or... trash the Install MacsOS High Sierra.app in Applications, empty trash & restart, then a new copy of a more recent version can be downloaded…new loc

If it's an IMAP account, delete it in Sys Prefs Internet Accounts then use "Other" instead of gMail choice to add it.
Most likely biggest factor is using Other in Mail setup, then using a Browser that doesn’t have gMail PW stored init to get the App PW.
It might just need an App Password separate from the gMail password…

Generate and manage third-party app passwords
Some older, third-party email apps (that do not use our Yahoo branded sign in page) require you to enter a single password for login credentials. To access your Yahoo Mail account on these apps, you'll need to generate and use an app password. An app password is a long, randomly generated code that gives a non-Yahoo app permission to access your Yahoo account. You’ll only need to provide this code once to sign in to your third-party email app.

Using app passwords with apps that don't support two-step verification (microsoft.com)
What about application passwords? Will that keep working?
If application passwords are being used for MFA (Multi Factor Authentication) along with basic auth as another auth mechanism, then when basic authentication is disabled, app passwords used for MFA will stop working too.
Where can I find more information?
There are several resources that we wanted to provide here as additional reading:
