Standalone Report Designer crashes on start when opening TRDP reports from Visual Studio. See the attachedimages below:

The stack trace came about after trying to open multiple files through VS and popped up after about report number 3 or 4. Lastly, for us "sometimes" the reports open, sometimes they don't. If it does open the report going through VS, then the Standalone Report Designer will randomly shut down/crash with no errors (after 5 to 30 minutes of active use. We haven't found a pattern for what makes the Designer crash.

So far, the Designer doesn't crash if started from the Windows Explorer.
