    Hello there,

    You can try to Reset the Network Connection and see if that helps.

    The command will remove all your existing connections, so we recommend you create a system restore point before executing this command.

    -Open PowerShell in admin mode.

    -In the PowerShell console, type in the command below and hit Enter to restart all network adapters and remove MUX objects.

    netcfg -d

    -Exit PowerShell when the command executes.

    -Now, open Virtual Switch Manager in Hyper-V Manager and try to create an external switch and see if the error reoccurs

    Hope this resolves your Query !!
