Windows 10: Ethernet controller issue

Hello Microsoft community,I just built a new PC recently, however, I am encountering issues with the ethernet controller. The device is disappearing from Network Connections unexpectedly during the day and I must use wifi to connect to the internet.It is not even visible in Device Manager. I am not doing anything that could explain that behavior.I have an i9-13900K on an Asus z790F mobo, along with a 3070 ti gpu.Any suggestion would be more than appreciatedThank you in advanceDimos
