It seems that you have enabled virtualization in the BIOS and created both internal and external switches, but you are still unable to connect to a Hyper-V virtual machine on your new Windows 11 Pro computer.
One possible solution could be to check if the RemoteFX adapter is enabled for the virtual machine. To do this, follow these steps:
- Open Hyper-V Manager.
- Right-click on the virtual machine and select "Settings".
- Click on "Add Hardware" and select "RemoteFX 3D Graphics Adapter".
- Click "Add" and then "OK".
- Start the virtual machine and try to connect to it again.
If this does not resolve the issue, you may want to check if the virtual machine is configured to use a virtual hard disk that no longer exists or if the virtual hard disk path is incorrect.
