Using High Sierra 10.13 my 2017 Macbook Pro freezes when connecting/disconnecting an external display

It's not completely guaranteed every single time, but the majority of times it does so. Mac OS Sierra had no problems whatsoever.

Every time I am forced to do a hard reboot which is annoying and can hardly be good for the computer.

I am connecting it through an Anker USB-C hub that has HDMI in. The HDMI cable is then connected to a Dell S2716DG. The laptop is specced as follows: 2.8Ghz, 16gb RAM, 512GB SSD, Radeon Pro 555.

I am grateful for any help fixing this!
