Hi,
it seems your dump is a first chance exception dump. Make sure that you change the Action time for un-configured first chance exceptions to NONE and then let the tool generate a second chance exception dump and that would be worth to look at.
If it generates one, analyze it using debugdiag and paste the stack and we can see why it is crashing.
For more information, please refer to the document
