I should receive a Yubikey 4 (USB-C) in the next few days. It will be much simpler for me to debug. I may ask you to test some patches.
Good news: I received the Yubikey 4 (USB-C). But I can't reproduce your problem. Removing the reader does generate just the expected logs. I am also using Linux 4.15.0-2-amd64 and libudev 238. But I note that inserting and removing the device does not generate errors by the kernel.

I suggest to search for a firmware update from Dell. Maybe the USB-C is (partly) bogus on your mother board. For example I found a BIOS update on Dell web site: Dell XPS 13 9360 System BIOS Importance: Urgent Version: 2.6.2 ,2.6.2 Older versions Release Date: 22 Mar 2018 File Name: XPS_9360_2.6.2.exe File size: 10.69 MB Description: XPS 13 9360 2.6.2 BIOS Tell me if a BIOS upgrade fixes the problem.
