Ethernet not working on M1 Max on MacOS 12.4

I have a UD-6950PDZ on a M1 Max with macOS 12.4 and the Ethernet port is not working correctly. Sometimes it seems connected (according to status in Network window but I cant open any url, always timeout connection. The only workaround is to use wifi…The dock itself is correct as I connect it to my Dell XPS and it works flawlessly. Its a M1 issue. If i use a usbc-c network adapter it works great (pluging the same network cable). But cant use the ethernet from the dock…Is it a known issue?
