External monitors using docking station stop working after update

Hi folks

I had an issue with my external monitors connected through a docking station after system update. I would like to mention that before update this was working perfect.

After bios update only display ports in the docking station stop working, the other ports in docking station like ethernet, power source, audio, usb, usbc, etc are working as expected.

My laptop is showing following code in the left side on startup only when i connect my docking station:

W GGGG-GGGG-GGGG O GBGB-BGGG

as per this documentation(My Framework Laptop (Intel 12th Gen Intel® Core™) is not powering on), the Gx12 means that everything is ok but the code after Orange is a binary code where G=0 and B=1, so, the hex code is 0x58. I found in this forum the following documentation:

But i don´t have idea what this code means…

As a workaround, i’m still using my docking station and i bought a hdmi expansion card, but i would like to attach monitors to docking station and use only one wire for everithing.

I would really appreaciate your support… thanks in advance.

Update: I tried with the right side ports attaching usb-c adapters there and now docking station is working fine with all my peripherals attached included charging and 2 monitors.

I’ll try to open laptop and try to figure it out if there is a problem with main board or IC.
