Error running 'TestUnoR4.ino' on Arduino Uno R4 WIFI

[ReneElizondo]

Hello,

Uploaded the TestUnoR4.ino sketch to an Arduino Uno R4 WIFI, when the code executes I get the error below (on the Arduino development environment serial monitor). Tried it on two different R4 boards and both gave the same error, I also tried it in different computers. The same type of error will not happen on a Mega board (al is good on that board).
