HP X360 HDMI no longer being detected via Type C Slot

[Ilambat]

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.

Thanks.
