Thunderbolt 3 dock Gen 2 with Thinkpad P1 - Freeze on connect and disconnect

When I connect or disconnect my P1 to the Thunderbolt 3 dock Gen 2 230W it freezes where the only way to get it to work again is to disconnect the dock, reset the laptop using the small reset hole in the middle bottom of the laptop, then plugging it back in to the dock and turning it on immediately.

 

While connected to the dock, if I sleep OR power down the laptop, then disconnect it. It freezes still. I have to reset before turning on the laptop disconnected. If I don't use the dock the laptop sleeps, wakes, powers down and up, perfectly fine.

 

If I leave the laptop open and running when I connect it to the dock it connects fine but then the graphics lag (as others have stated in another post).

 

I have all the latest firmware and drivers according to Lenovo Vantage.
