Thunderbird calendar - events missing after upgrade

My original problem was a blank Thunderbird window (see below) but now the problem is with my Thunderbird calendar -- specifically, all my events are gone.

Previously: my Thunderbird mail client began opening up almost entirely blank, as shown below. I can still click "Write" and successfully send messages, but I can't see any folders or messages in order to actually read my email. I was running Thunderbird 102.3.3 (64-bit) under ubuntu-snap-build 1.0, on Ubuntu 20.04.2 LTS (64-bit), and GNOME Version 3.36.8. I tried enabling and disabling Hardware acceleration and restarting Thunderbird, but to no avail.Reverting to Thunderbird 102.3.1-2 via snap revert thunderbird 259 had no effect. My (partial) solution: going to https://archive.mozilla.org/pub/thunderbird/releases/ and then selecting the very latest (beta) version of Thunderbird, unpacking & installing it. I then ran "./thunderbird --ProfileManager" first to make sure that I was selecting my old user profile, and -- bang! -- I can now see all my emails, but I still cannot see my Lightning Calendar appointments. Specifically, the version I'm now running is the Linux 64-bit version of 107.0b1: https://archive.mozilla.org/pub/thunderbird/releases/107.0b1/

So: partial success, but my calendar is still empty. Suggestions?

My solution was just to copy a bunch of Thunderbird files from my other computer to this one (with the broken calendar). Specifically, I copied over to my broken installation the "prefs.js" file in my Thunderbird profile directory, and all files in the profiles "calendar-data" subdirectory. Even though that old computer was running Thunderbird 102 and the new one is running 107beta, the calendar now loads successfully.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
