maybe go to Settings > apps > google assistant and clear data.
Could also try reinstalling it from Google Play https://play.google.com/store/apps/details?id=com.google.android.apps.googleassistant&hl=en_CA
Also want to make sure google assistant is default assist app
What language/country is your phone set to?
