Hi @MolKas4me, did the Host leave the meeting? Or did the host's camera go black, therefore, that's what you're seeing as a participant within the meeting? I'd be sure you're up-to-date with the latest version of Zoom. Here is how you can update your client
Your webcam's screen may appear black or not recognizable in Zoom if no permissions are given to access the Camera. Looking forward to your response! 😄
