Hi matthiasb22762405,
Thanks for checking in. Sorry that you have not heard back from the team yet. Is there anything more you can tell us about your system? See, How do I write a bug report?
In other cases like this, the webcam .dll had been interfering. I am not sure what mlc.dll does or controls. Learning a bit more about that item might be helpful.
I hope we can assist you with this shortly. Sorry for the frustration.
Thanks,
Kevin
