Yesterday i made a home assistant upgrade (0.88.2). After few minutes home assistant stop to work… Closed and reopened… blank screen…

Uninstalled 0.88.2, cleaned working directories, virtual environment and so on, re-installed 0.85.1 (with default configuration.yaml) and nothing change (blank screen).
