AmneziaWG Interface Failure Due to Missing Kernel Module

The most frequent cause for the 'Unknown device type' error is that the 'amneziawg' kernel module is not installed or available for the currently active kernel version. To diagnose this, run the command 'modinfo amneziawg'. If the system returns 'modinfo: ERROR: Module amneziawg not found', the module is absent. Additionally, verify the active kernel version using 'uname -r' to determine if a recent system update has caused a version mismatch between the installed kernel and the available module.
