I wanted to give it a try, unfortuantely I fail already at the first screen. Selection a location the backend fails at creating the timeline:

    "error": "opening database: pinging database file: invalid uri authority: D%5CMy%20Timeline%5Ctimeline.db_foreign_keys=on&_journal_mode=wal&_txlock=immediate&mode=rwc"

It seems it is trying to parse windows file paths as URIs, and thrown off by the ":" in windows file paths.
