I think it should be PT111600S. Does it work when you change the iCalendar (add the missing T)?
Steps to reproduce:

Can you provide more information about the exception (complete debug info)? Did you already verify the iCalendar?
We couldn’t reproduce this problem yet and don’t know where this problem comes from, see
The only thing we know is that it’s related to system caches. You can uninstall DAVx⁵, then install it again and it should work again. Or alternatively you can update your Android version.
Does this help?
