TB.x64.en-gb.78.14&91.1.0.console.logs.home.calendar.txt

FYI, about local Home calendar being empty after upgrade, I could **not** reproduce the issue, here are the steps followed...

- Install TB 78.14 en-gb on Windows 10 Pro x64 21H1 10.0.19043.1165
- Setup a new user profile
- Don't enable email - just close the email setup wizard
- Enable Home calendar in Calendar view
- Import .ics file (a known working calendar exported into .ics file via TB) into the Home local calendar.
- Exit and restart TB
- Gather console error logs - see attached part 1
- Exit TB
- Install TB 91.1.0 en-gb x64 ==> TB upgrade
- Open TB
- Home calendar is still enabled, and even items both vevent and vtodo available in TB 91.1.0 after upgrade -
-- I can also record new items into the calendar
- Gather console error logs - see attached part 2

Hope that help in some way...
