I thought there might be a problem with Thunderbird 133.0, so I attempted to install version 130 over it. I was told it was incompatible with version 133.0, so I uninstalled version 133.0 and installed version 130.
Since then, Lightning Calendar has been missing, even when I reinstalled version 133.0. The Events and Tasks tab is missing. Calendar does not appear in Add-ons and Themes. There is no trace of it anywhere. I uninstalled Tbird, deleted all of the folders for it and reinstalled Tbird, again. No luck.
