I am unable to find any calendar entries. I bet i was using the Lightning addon or something and possibly TB updated recently (78.10.0 (64-bit)), maybe i have not rebooted OS.
I am unable to find any calendar extension among addons in TB.
When i launch TB via command line, i see:
console.warn: Lightning: {“result”:11,“message”:“database disk image is malformed”,“ERROR”:1,“INTERNAL”:2,“PERM”:3,“ABORT”:4,“BUSY”:5,“LOCKED”:6,“NOMEM”:7,“READONLY”:8,“INTERRUPT”:9,“IOERR”:10,“CORRUPT”:11,“FULL”:13,“CANTOPEN”:14,“EMPTY”:16,“SCHEMA”:17,“TOOBIG”:18,“CONSTRAINT”:19,“MISMATCH”:20,“MISUSE”:21,“NOLFS”:22,“AUTH”:23,“FORMAT”:24,“RANGE”:25,“NOTADB”:26}

btw, it can help to restore backup of the files in this directory: /home/me/.thunderbird/namehere.default-release/calendar-data/ when TB is not running.
