Comment 84 for bug 1945368

Am going to try this again (comment 78) after I re-install TB 78.1. My separate installation of TB 78.1 auto-updated to TB 91.2.0 at some point without my knowledge (note there are *no addons installed at all*) and *home calendar and tasks lost again* in that installation now. I am sure they are in the local.sqlite file as before, but not showing for whatever reason. Other calendars appear unaffected, still seem to have all events in them. No add ons, I am not syncing with any other calendars or applications. Will repeat steps as I did before to install TB 78 and remember this time to tell it not to update, set up bare profile with no email, etc., just calendars.

Before I realized the update had occurred, did try pasting in storage.sdb from a 09/22/2021 backup file, TB version unknown, with no showing tasks changes. Confirmed by changing task filtering several ways.

Note 1: Have installed TB 78.13 and imported .ics calendar into home calendar. All events and tasks show up like a champ. (No email set up, no add ons, just bare.)

**Note 2: Also installed clean TB 91.2.0 and when I tried to import .ics calendar, it appeared to just stall on "loading items" - see screenshot. Only took seconds in 78.13. Should I wait longer? Why will it not import the .ics? (exported in this format from TB)**

Note 3: Part of the problem with the TB 91 update could be the advice to import csv calendar as I opened this file by itself and noticed that it has lost a ton of data - those tasks I showed in file uploads "Call Union..." are not in the .csv.
