On Linux/macOS or in secure environments, the process may lack read access to a configuration directory or write access to create a “new” interface. In such cases, the error message is a red herring for underlying file system restrictions.

I ran into the dreaded while trying to launch a virtual machine / network emulator / proprietary hardware tool (depending on your context). The error essentially means the software or driver expected a specific network or device interface configuration, but that config was either corrupt, missing, or pointing to a phantom interface. internal error 0x0b interface config missing new

The keyword “new” often refers to a dynamic configuration that the software tries to generate on the fly—for example, a new virtual network interface, a new input profile, or a new overlay. If the template for that “new” item is missing, you see this error.
Use ip link show or ifconfig -a to verify if the interface exists. If it is a virtual interface, ensure the corresponding kernel modules are loaded using modprobe . 3. Manually Generate the Configuration File

Given the phrasing, this error most plausibly occurs in a kernel-mode device driver during the IRP_MN_START_DEVICE or a similar start-device routine. When a driver receives a request to start a device, it must retrieve the "new" configuration assigned to that device by the Plug and Play (PnP) manager or firmware (e.g., ACPI). The driver expects a structured data block—often called CONFIGURATION_INFORMATION or DEVICE_DESCRIPTION . If the pointer to this block is NULL , or if the block lacks a required "New" version tag (indicating that the driver attempted to reuse an old, freed configuration), the system will raise an internal error.
