imac ethernet service disappear from the location>add service menu

Hii. imac retina 4k 21.5", 2017. macOS Ventura 13.6.5. [the problem is from 13.5.4. updating the OS didnt solved the problem]

Suddenly I found that I don't have an internet connection via ethernet.

Try to create new location - dont have any ethernet option, delete the ethernet from my current locaion - can't add it back.

I ruled out an option of bad ethernet cable or modem.

Tried to close/open en0 via the Terminal - It's say that its not exist.

At systen report founf this info:

Also I have tried deleting .plist file from the systemConfiguration at the preference library, and done a SMC reset. None works.

currently, I connect the ethernet cable via usb-adapter and create a usb 10/100/1000 lan. It's works fine.

But what appened to my normal ethernet service, directly to the ethernet port?

Thanks in advance
