3.1.5 crashes upon selecting "google" in settings->account

As the title says. Instead of the expected fields to enter username and password for the google account the application crashes. Anonymous works.

3.1.5 from fdroid, updated today. Problem didn't exist in previous version (also from fdroid, 3.1.3 iirc). Lineageos 16, redmi note 7, no gapps.
