Cannot create list

The list is not created.
Only when I reset calendar connection it starts working but for a while, soon I cannot create it again. Why?
Also cannot remove the list connected to Icloud sync for some reason.

Thanks for using GoodTask. Do you have Reminders app working properly? Please check if it works well. GoodTask is based on Reminders database so it depends on Reminders app. Thanks!

Reminders works and can create/remove lists
But GoodTask no

Would you share screen recordings to ? It would be helpful. Thanks!

Just sent email to you
