Missing interop type marshalling data

[Tyler]

Multiple users have generated a crash log via AppCenter that suggests I have some sort of Telerik error, but I haven't been able to duplicate it myself. Here's the error.

ComCallHelpers.Call (__ComObject, RuntimeTypeHandle, Int32, Void*)

EETypeRva:0x00067310(System.Runtime.InteropServices.MissingInteropDataException): System.Collections.Generic.IList`1[Windows.UI.Xaml.Automation.Peers.AutomationPeer] is missing interop type marshalling data. To enable interop type marshalling data, add a MarshalObject directive to the application rd.xml file. For more information, please visit http://go.microsoft.com/fwlink/?LinkID=393965

Does anyone have any thoughts about what this might be related to? Thanks!

Hi, 
I couldn't find a similar issue reported before. I have searched in tickets and forum threads and such exception wasn't reported. 

I am not sure why the crash happens. I will need a sample repro for further investigating the behavior.

Hi Didi. Thanks for the response! Unfortunately I've never been able to reproduce this error myself. I've only seen it in the crash logs, maybe happening once or twice per week for a while now. If I'm able to collect any more information or figure out how to reproduce it, I'll post back here.
