First, you need to install the previous version of miui eu ROM and add your fingerprint.
After this first install, install xiaomi.eu updated rom (do not wipe anything). Fingerprint will work now but Google play may crash.
If so, go to "settings - installed apps - show all apps" and force stop, clear all data and caché from "Google play store", "google play services" and "google framework".
Reboot and everything will be ok.
