Can't login using Google account

Hello, I've reinstalled my SwiftKey after OS update, and found IT impossible to login to my account using Google. Solutions mentioned in previous threads won't work: neither logging in to data...., nor clearing my cache, even the newsletter box doesnt help. Whats going on? I've been using swiftkey for years, reinstalled it a number of times, and this is the first time something like this happens to me. OS: android 10 (Oxygenos) SK: 7.5.7.4
