Do you see your Virtual Switch information in the Control Panel \ Network and Internet \ Network Connections section? If not, you can try creating your Windows Phone Emulator Internal Switch from Hyper-V again to see if this fixes your problem. Follow these steps:
1.) Open Hyper-V
2.) Disable all existing configured phone emulators.
3.) Click "Virtual Switch Manager"
4.) Click on "Internal Phone Phone Emulator Switch"
5.) Remember what settings are displayed there (because you delete it and recreate it)
6.) Uninstall the existing “Windows Phone Emulator Internal Switch” by clicking “Uninstall”
7.) Click "Apply" and "OK"
8.) Re-create the “Internal Phone Phone Emulator Switch” by clicking “New Virtual Network Switch” and use the same settings that you remembered in step 5.
9.) Then try F5 from Visual Studio, which should set up a new emulator on the virtual virtual switch.
10.) Now the error will be resolved. if not in hyper v, start the Windows phone emulator → then click "Connect" (now starting the emulator from hyper v)
11.) Then try F5 from Visual Studio - to start the emulator (it took some time to start in my case)
