LG Ultrafine crashing MacBook - Panic Report - UPSB: thunderbolt power on failed

I know it is rather late for a reply, but I had the same problem at 4:02 AM this morning. The day after I returned the Choetech Thunderbolt Power cable that I bought for $63 on Amazon and went back to the original Apple supplied cable (which seems a little looser in the LG).

The problem started happening a couple of months ago (I bought the same Macbook 13,3 with the LG in December 2016. Had the LG replaced because of screen issues a short time later.)

The restart only occurs early in the morning, but I frequently (5 times a week?) have to jiggle the cable to get the display to come on, which is one of the reasons I bought a replacement.

I have pretty much the same dump as you show.

Flummoxed!
