Same Problem here, no luck so far.
Sometimes is works after reboot of windows.
Windows 10 64
Chrome Canary 63.0.3211.0
Tried 64 Bit and 32 Bit Videostream versions, uninstalling previous ones
Tired removing the folder @ Users/.../AppData/Local/Videostream
Tried disabling Windows Defender, Comodo Firewall, Avast (disabled them completely)
Tried running everything with admin rights
