Product: HP ZBook Firefly 16 inch G10 Mobile Workstation PC (740J1AV)
Operating System: Microsoft Windows 11

After a software update, a driver failed to install correctly (DisplayLink - Display - 11.1.2.27577.0) with error code 0x802480077

 

This caused the monitors to not display correctly when connected via USBC dock. The monitors show blank screens and they do not show up at all in Display Settings, however they do not power off (which they would do when getting no signal).
I tried reinstalling this driver from the DriverLink website, however the issue persisted.
I then tried to restore the PC (kept personal files), however the issue persisted. I tested this across several docks (official HP, WavLink and Lemorele (both HDMI and DP), all with the same results. When plugged in directly to the HDMI post on the laptop, the individual monitors both work. It is only when plugged into the dock that the issue occurs (even if only one monitor is plugged into the dock, it will still not display).
