Mac OS crash when thunderbolt ethernet is UNPLUGGED

I'm experiencing a very strange issue.

When i unplug thunderbolt ethernet, in 1-2 minutes my Macbook Pro Retina 15 (Mid 2015) hangs with a black screen (keyboard light is on) for 15-30 seconds and than shuts down.

It happens even if the ethernet cable is unplugged (so i'm actually using wifi).

System needs the adapter to be plugged in.

same issue in this post https://discussions.apple.com/thread/7602273 and I did everything

MacBook Pro 15", macOS 10.14

The problem should be solved once you turn off buggy Thunderbolt LAN Ethernet driver. Here are the steps:

1) reboot with CMD+R pressed.

2) open Terminal

3) csrutil disable

4) reboot in normal mode

5) sudo mv /System/Library/Extensions/AppleThunderboltNHI.kext

/System/Library/Extensions/AppleThunderboltNHI.kext.BAK

6) reboot with CMD+R pressed

7) csrutil enable

8) reboot and forget about problem
