Arduino Uno Wifi Rev 2 - Can't load any WifiNINA examples

Specifically WiFiUDPSendReceiveString. I am getting the following error when I upload the sketch:

Arduino: 1.8.8 (Windows Store (Windows 10), Board: "Arduino Uno WiFi Rev2, None (ATMEGA4809)"

Sketch uses 11750 bytes (23%) of program storage space. Maximum is 49152 bytes.
Global variables use 669 bytes (10%) of dynamic memory, leaving 5475 bytes for local variables. Maximum is 6144 bytes.
Resetting the board
Failed to reset the board, upload failed
An error occurred while uploading the sketch

Please help. I really appreciated it.

Is the issue limited to the WiFiUDPSendReceiveString sketch, or does it also occur if you attempt to upload the minimal File > New sketch?
