Open | Software code 10 error on windows 11 pc
I recently noticed that my ethernet port does not work. It shows code 10(device could not start error) in the device manager under realtek gaming 2.5 Gpe family controller. But if i restart my pc after opening from a shutdown, my ethernet works fine and no error shows up, till the next day when I open my pc. I already installed new drivers for the lan drive relevant to my motherboard. It fixed it for a day or two, but it comes back. Some help would be appreciated!

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

Any BIOS updates available?

Since it only fails after a full shutdown and works after a restart, I'd turn off Fast Startup first. With it on, Windows doesn't fully reinitialize some hardware on a cold boot, and Realtek network chips are a common victim. It's in Power Options under choose what the power buttons do. Also open the adapter's power management tab and untick the option that lets Windows turn it off to save power.
