Hi @stankdawg - thank you for trying various workarounds/fixes. I am in the same boat, with no real solution, and no clue from the PMS server log. And as for the database being corrupt, it seemed to work when I downgraded / installed version 1.17 over 1.18, and also seems to work with 1.18 using the Android Plex app.
It appears another user is having a similar experience (here).
