Arduino Uno WiFi Rev2 freezes

Official Hardware Classic UNO WiFi Rev2
1

I found this blood pressure monitor hack using Arduino on YouTube/GitHub, and it works well with an Arduino Uno. When I run the sketch to an Arduino Uno Wifi Rev2 and open the serial monitor, it freezes when it comes time to display the blood pressure data. All connections are directly connected to the board. Any suggestions on how to fix it?

Without a proper schematic showing how you wired it I have no suggestions.
