After installing the 115.0b3 beta over a current release version, I have lost Calendar event data, Sent messages, and Local Folders.

I did an Import from AppData Profiles where I have .default and a .default-beta Profiles. I imported from .default. This returned my Local Folders. But no Calendar events or Sent messages. Is there another location where I might find or import my missing data?

I have a system backup from 6 months ago, with the same Thunderbird Profile name. Should I import this, and would it give me my missing data?

I saw a 2 year old Support solution using SQLite Manager. I have not tried this yet on the 115-beta. Should I install the SQLite Manager and enter some command line stuff?

I can send my Troubleshooting Information file if required.

I would suggest first off reinstalling the release version and see if it connects to your release profile. If it does not go to the about :profiles entry in the more troubleshooting information on the help menu and press the launch button for the default profile.

Does it workout and launch?
