2] Remove additional network adapters
If you have used several external network adapters recently, your computer has stored information about them. As a result, you might encounter issues with a specific adapter.

To do that, open Device Manager, expand the Network adapters section, right-click the network adapter you want to remove, and select Uninstall device.

3] Check User Rights Assignment
To check the User Rights Assignment settings, open the Local Group Policy Editor, and go to this path:
Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment
Double-click on the Access this computer from the network setting and check if your user account is listed or not. If not, click the Add User or Group button, enter your username, and click the OK button.
4] Check Device Guard settings
If you have enabled virtualization-based security through the Local Group Policy Editor and the settings do not match your current virtual machine, you will encounter issues with various features, including network adapters. That is why it is suggested to disable the custom settings and try again.
For that, do the following:
Open the Local Group Policy Editor on your computer and navigate to this path:
Computer Configuration > Administrative Templates > System > Device Guard
Double-click on the Turn On Virtualization Based Security setting and choose the Not Configured option.
Click the OK button to save the change. Once done, close all windows and restart your computer.
However, if you want to do the same via Registry Editor, open the Registry Editor and navigate to this path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios
Create a new key named HypervisorEnforcedCodeIntegrity. Under this, create a new DWORD (32-bit) Value named Enabled. Double-click on it to set the Value data to 0.
Save the changes and restart your computer.
Alternatively, you can delete this REG_DWORD value as well.
