I tried to replicate your situation without success. i connected a usb-c to ethernet adapter to the 2nd usb-c port while a zbook 15 g5 is connected to a HP Thunderbolt dock with display, kbd, mouse, etc. attached, and the ehternet adapter worked immediately
before going any further, i would run HP Image Assistant and update BIOS and drivers and test again
also, what version of Windows 10 are you running?
I work for HP. However, all opinions and comments are my own.

Product Number: 3AX12AV
System BIOS: Q70 Ver. 01.10.00 - 01/03/2020
OS: Windows 10 Pro Version 1909 Build 18363.815
The BIOS detects the device (it is shown as a boot option), but it is not detected under Windows.
Tested with both a Sandisk SSD storage device as well as a Galaxy 10 phone.
The above steps are 100% reproducible (not sporadic).
It seems it is related with thunderbolt security, but I cannot figure why.
The following is the [FN+Esc] usb-c output:
