I'm on 20.04 and a variant of this problem occurs to me. Randomly and without warning, about twice a week, I'm prompted to re-authorized my Google account from Evolution. I'll just be sitting at my my computer, not even using Evolution, and suddenly the authorization window will pop up. It doesn't even remember my Google password so I have to re-enter it manually.
