My Gmail account is not showing up in Mail. The account shows up in the list of internet accounts and calendar dates are synchronized in Ical, but next to the email setting the status button it only shows "checking."
This is not an issue on my other devices that are still running on Catalina.

I finally got it to work. In case you run into the same problem: I exported my TLS certificate that I had in Keychain/login on one of my other Macs and then imported that certificate into Keychain on my new one, setting it to always trust in all categories. In Mail account settings /server settings/ edit smpt/ advanced, I could choose that certificate now and uncheck insecure authentication. It took a few minutes for the account to finally become active.
So I figured out how to delete the keychain but I still get Authentication failed when trying again to add my gmail account.🥲
