Experiencing the exact same problem on a Dell XPS 13 9630 since upgrade to kernel 5.3.0-46.
When problem is triggered, I can still move the mouse pointer for 2-3 seconds but can't interact with the desktop or any apps (clicking or typing does nothing). After that the mouse pointer stops for about a second. And then it all comes back; the clicks and keys that I types during the freeze comes flushing back... Also noticed that when I'm on a telco, sound and video is completely unaffected throughout the freeze.
