Release configuration only exception in SfSchedule.

I'm seeing an exception and my Android app crashes in release configuration build.  Everything works as expected in Debug build.  I'll start a simple sample app to see if I can narrow it down, but would appreciate any help you can provide.

Here is the exception from the device log.

Hi John Prass,  
Thanks for contacting Scyncfusion support.  
We have checked your query and attached call stack. We have prepared the sample for the same and tried to reproduce the issue.  But the issue is not reproduced in our side. From the stack trace provided we are able to get that the exception occurred from SfSchedule, so please modify the sample attached to reproduce the issue and provide the clear replication procedure to reproduce the issue in order to provide you with the solution faster. Please provide us the details of the properties set to the SfSchedule to reproduce the issue.
