WiFi Networking

I get the error ioctl esp32Command failed OperationNotPermitted when the app tries to execute the wifi code example provide on the Networking example. But I do recall getting this exception when I downloaded the OS. System.IO.FileNotFoundException: Cannot Find Source File
File Name: C:\users\arg\AppData\Local\WildernessLabs\Firmware\MeadowComms.bin

I have the latest OS download Beta 5.1
