Why my calendar clear when I installed the beta version and why can't add events?

I downloaded and installed the latest beta version of Thunderbird and when I did, my full schedule of events and appointments disappeared and I cannot add anything to the calendar.

I do not like this beta and restore the previous version which worked very well.

Each version of Thunderbird has a matching version of lightning. The calendar is empty because you have not upgraded lightning when you uploaded the beta version of Thunderbird.

Lightning versions are here. Get the software to match and your events will load up.
