ColorCamera node crashes when setting FrameSyncMode::INPUT in DepthAI

I'm experiencing a crash when setting frame sync mode on a ColorCamera node in DepthAI. My pipeline works perfectly until I add color_cam_node->initialControl.setFrameSyncMode(dai::CameraControl::FrameSyncMode::INPUT); to my ColorCamera configuration, which causes a crash. The identical call works fine on MonoCamera nodes in the same pipeline. I'm running Ubuntu 22.04.5 with ROS2 Humble and the latest DepthAI. Is FrameSyncMode not supported on ColorCamera nodes, or is there a specific initialization order required? All other initialControl settings (sharpness, denoise, etc.) work without issue on the same node.

The FPS of the node must be the same as the one driving it. Depending on the device, the camera might not even be connected to the FSYNC signal from the other two cameras, causing a stall.

Thanks @jakaskerl

All cameras are set to 30 FPS.
