I uninstalled user_saml and installed version 3.1.2, now everything works again: https://github.com/nextcloud/user_saml/releases/download/v3.1.2/user_saml-3.1.2.tar.gz

Changed the title, NC 20 does not seem to have anything to do with it, more likely the user_saml update, as 3.1.2 works just fine.
