Hello,
None of our runtime is supported on VS 2013 yet. CR for VS Service Pack 9 will once it's released in a month or so...
For now all I can suggest is possibly wrapping all CR API's in a try/catch and add logging to your app to see which API's it's hanging on, it could be something else is failing and not being handle properly so the close method hangs... Maybe the report did not even load....
