Thunderbird calendar won't update

Last week I had a Windows 10 update to version 1709.

Now I can open the Thunderbird calendar, but I can't edit or add any new events or tasks. The calendar is "frozen". So totally useless at present.

Any ideas how to solve this?

After re-starting Thunderbird a couple of times, then re-booting the PC, the calendar is now working again. Relief!
