I am having the exact same issue with my VIXIA HF G50. I am not using Zoom. I am simply plugged into a Blackmagic ATEM mini. All it does is receive the HDMI signal from the camera via an HDMI cable, it does not interact with the camera in any way. The camera itself is freezing. Moving the power switch to "off" does nothing. The camera stays on, displaying the frame it froze on. I am willing to bet the OP is having the same exact issue. If he is "streaming" then it is definitely a camera issue, like mine.
I'm sorry to hear your camera is freezing. If it is freezing to the point where the display doesn't turn off when you flip the power switch the camera most likely needs to be serviced.
Before sending it in it would be good to check a couple of things. The first is to load a different battery in the camera. Sometimes if the battery is malfunctioning it can cause freezing like this. The next thing is to try loading a different memory card in the camera. Sometimes if a card is corrupted it can cause this kind of issue. If the issue continues next try a different HDMI cable, and finally if the same thing is happening try connecting the camera to a different HDMI device to see if the freezing keeps happening. Sometimes if the cable is degraded or if there is an issue with the first HDMI device you were trying they can cause freezing.
If the freezing keeps happening after checking each of those things at that point we would recommend sending the camera in for service.

Thank you for the reply. It happens with a battery, it happens with a battery and plugged into the power supply, it happens without a battery and plugged into a power supply. I do not have a memory card installed. Probably worth mentioning, the firmware is up to date, and has been since before the issue started. I will try different HDMI cables the next time I have an opportunity and report back.
