To diagnose the issue further we need the following information.

  2. Generated output file(s) - if you were able to generate one
  3. Code you used to generate the output.

Release channel:
Latest official builds, and Release channel, are ready for production usage, however the developer channel builds do not get the same amount of testing and can be in a state of change.
