Calendar Bug on Thunderbird Update

Gene

The last three Thunderbird updates totally erased my calendar information. I have backups which help to recover information but it is not acceptable for this to happen. Windows 10 Home latest update. Thunderbird 115.6.1 (64-bit) (erased calendar data) Hopefully this will be addressed as I really do not wish to change to another mail client as, up until now, Thunderbird has been very satisfactory.

Are you using any calendar addons? Like I understand tbsync has been updating and outlook calendar entries have issues until the EAS add-on for outlook gets to update following an restart of Thunderbird.

No calendar addons
