Unreal 5.4 switchboard and livelink problem

Hello, I want to ask about the new Switchboard on Unreal Engine 5.4 I found some trouble when launching the render node and editor. The server name automatically added a random set of name for example my PC or server name is DESKTOP-546 at the bottom left of the switchboard it says DESKTOP-546_wit8172u, why is there an extension to my server name. It doesn’t only happen on switchboard it also occurs on the multi-user session. The result is that I can’t launch the render node and editor from switchboard.

There’s another problem regarding the 5.4, the livelink preset that I’ve inserted inside the editor and switchboard seems to be not working at all. The same case as in 5.3 where we need to save the editor to get the livelink to work again as usual. The problem occurs when we move the nDisplay actor inside the editor.

Anyone know the fix to this problems ??
