unimplemented function bthprops.cpl.BluetoothGetRadioInfo
@kisak-valve Hopefully that's a false-positive, it appears Bluetooth functionality is required by the optional(?) ForceTubeVR plugin for Unreal Engine 4.
As an aside it also appears Contractors uses the open source Secure-Client anti-cheat plugin (currently Windows-only).
Unfortunately the issue still remains with the current Proton and SteamVR releases.
Nothing extracted yet.
