The gimbal was making your camera freeze?
Yea, strangest thing. I checked the DJI forums, its been happening on a few RS models and Canon camera's. I would put the gimbal to sleep, turn off the camera, then go to turn it back on and nothing. Whole camera locked up, only way to get the camera to power back on was to pull the battery. I have some right angle mini HDMI adaptors with an led status light on them, when the camera would be locked up, those status lights are still on. Got on with DJI chat, sent them a video, swapped USB cables, HDMI cables, downgraded gimbal firmware, updated it back to the latest, same issue. This literally happened out of blue. Everything works fine (joystick, shutter control, etc.) until I put the gimbal to sleep or power it off. I plugged the camera into the pc to make sure the USB-C port was working, no issues, can turn the camera on and off without issues.
