Google Login Issue

Very odd issue. Never had this myself but I could offer some advice. Given that you know your password and everything, maybe try uninstalling and reinstalling the app?
If that doesn’t work, you could try resetting a couple things on your phone. In settings go
General > Reset try resetting network settings and location and privacy settings. This will disturb some things your phone had picked up on over the course of you having it, but this could work. It’s fixed issues for me in the past. The messing with the phone is annoying but once u set everything to normal again, you’ll forget you even did it.
Hope that helps, good luck.

If you installed an app recently remove it.
