X1 Carbon 5th Gen (20HQ) Thunderbolt Controller Crashing

My Thunderbolt controller keeps crashing and prevents me from being able to use my USB-C dock (it still charges, but no USB/displays).

To restore functionality, I have to shutdown, hold the power button for 10s, then boot up, but that's only a temporary fix.  The controller inevitably crashes within minutes/hours of booting up and I have to repeat the steps.  Sometimes my external displays continue to work after the Thunderbolt controller crash error comes up, but if I undock/redock they don't work. 

 

I've updated my BIOS (N1MET52W), Thunderbolt driver (17.4.78.500), Thunderbolt controller FW (N1MTF25W), and USB-C Dock FW (3.7) to the latest available, but nothing has helped.  Sometimes the problem will go away for a few days then come back. 

 

Has anyone run into this?

Thanks!
