Docking station not detecting displays over any port

HP Recommended
HP Elite USB-C Dock G4
Microsoft Windows 10 (64-bit)

I have an HP Probook 430 G4 and HP Elite USB-C Docking station G4 which are compatible as per HP docs. The OS is Windows 10 with the latest updates. No company restrictions or anything.

I plug my monitor via HDMI in the docking station usually, as well as all the other peripherals, while only one USB-C goes into the laptop which works for charging as well.

The thing is, it worked flawlessly until an update callup came from Intel, Microsoft, HP for a bunch of devices, including the graphics card, the OS and the BIOS and probably for the docking station as well. After that, it kept disconnecting.
Now, the monitor doesn't recognize the docking station at all, while the all the devices in the port freeze (mouse and keyboard). This applies for both HDMI and DisplayPort ports, so everything display-related. The HDMI works fine in the laptop and Displayport I can't test because I don't have one.

I tried re-flashing the docking station with HP provided firmware, it installed successfully prompting me do to a power cycle at the end. HP has zero mentions regarding power cycles so I simply disconnected the power source, the USB C from the laptop and held the power button of the docking station for about a minute or so, with no success.

The normal thing to do would be to test it with another compatible HP laptop to eliminate the possibility of having faulty ports, firmware or the dock at all, but I don't have one.

The forums are filled with questions like these, but I haven't found a viable solution yet. Has anyone faced similar issues and managed to solve them? There is one issue dating back to 2018 that fits exactly my problem, yet it mentions the latest firmware will fix this. That firmware is from July 15 2018 and installing it may have just crippled the dock alltogether.
As mentioned before, it worked but stopped after updates. So there isn't any power issue, cable issue (changed 2 hdmis and one displayport).

Which document you are talking about ?  I can only see 430 G4 under HP USB-C/A Universal Dock G2 dock on page 39 of the following list:

It's a probook 430 g6 I'm sorry. Got confused between the G in thr laptop vs dock name. 

 

The dock (USB C dock g4) is listed on page 6
