A video conference can not be stablished

My Messenger on my PC gets closed after I push the video conference button.

I uninstalled and installed Messenger again, but the problem still there ... I con not make a video conference. It shows me the window for the video conference for a second and then it gets closed.

Does somebody has en idea, what the problem could be?

Thank you very much
