Got the same issue, when i change the time of day the contz pack crashes to desktop. They are aware of the problem and it seem to be solved. The only thing is we have to wait for an update to test this issue..
As a buyer (not a gold member) we don't get these updates, so we can't test this issue. But i am sure the contzpack standard causes the issue. It is reported by me, and i got this answer to test it in the next update. Unfortunately, we as buyers of the 2019 version are stuck with version 100240 and don't have an update to test the issue.
I got the same issue in Tane by the way, and reported it frequently. But only recent i discovered its the Contz pack that causes it.
