Interesting. Are you able to reflash the device?

I do not suggest you do this unless you are comfortable with the flashing process. Even so, it would certainly be a great idea to FLASH A SDCARD NOT THE PHONE eMMC.

I only suggest this possible route to see if it is software or hardware related.

I've been running from multiple reflashed SD cards, I haven't attempted to reflash the eMMC.
eMMC has original UBPorts edition Ubuntu Touch (updated/upgraded over wifi to Version 5).
The problem occurred after a kernel update while running from SD.
Booting from eMMC or SD(Phosh, Mobian, Sxmo, ui-free-postmarketOS) produces usb/ethernet error.
I'm considering replacing the usb-c-side-board (optimistically).

What advantage does eMMC reflashing have over SD reflashing?

Try putting it into the ubports direct flash mode.  
Take out the sdcard, put the battery in and hold the volume up button and power button until the LED goes red. It should hit that "Update" window from ubports, then plug the phone in and see if your os detects the device.

The USBC boards are cheap enough. Do you ever plug it in without the cover on?
