May it be that you've just overlooked that line? Maybe use
netstat -a -n | findstr 18181
or
netstat -a -n -b > C:\ns.txt and then search ns.txt in notepad?
This is how it looks on my Windows 10 machine (relevant two lines):
  UDP    0.0.0.0:18181          *:*                    
 [ffplay.exe]

There is a free gui tool "CurrPorts" similar to netstat

Btw, maybe use VirtualBox then? Instead of Hyper-V.
