HP X360 HDMI no longer being detected via Type C Slot

Spectre x360
Microsoft Windows 10 (64-bit)

My laptop has been working fine until this afternoon. HP Assistant did a BIOS update on the laptop.


Since this update, the laptop has stopped recognising my hdmi adapter in the Type C slot and no longer extends my monitor.


Can someone advice what to do? My drivers are all up to date.
