The issue might be related to the cable, can you please try another original cable and try again, and if it possible please try another PC as well.
If the issue continues, pleasebring the device to a Samsung Service Center.
I've been using USB 2.0 to USB C for the past month and it has been working flawlessly for me. Now, today, for seemingly no reason, it takes 6 seconds for every interaction to update on my monitor.
I haven't changed any settings, or done anything different. These problems have popped up for no reason.
