EDIT: Nevermind, it solves the problem sometimes, but not always.
I’ve found that in version 0.31.1, the only way I can reliably start HASS and get to the frontend, is to delete the home-assistant_v2.db file before starting it. Otherwise, sometimes it starts all the way up, and other times it hangs loading some component and the frontend is never available.
I was having long hangs on start and stop so last night i migrated to a MySQL DB and now i am not having any issues. Maybe give that a shot? Also how are you installed, might be worth trying a docker installation.
