Welcome to the forum
According to the topic title you are using a Uno R4 WiFi
error: avr/io.h: No such file or directory
#include <avr/io.h>
The error message seems to indicate that an AVR processor is expected by the library but your Uno does not have an AVR processor
Conclusion. The library is compatible with a classic Uno/Nano etc but not with the Uno R4 boards
In the Arduino IDE select from the main menu: Tools -->Boards --> Arduino AVR Boards and then at the end of the list: Arduino Uno Wifi
would that help ?
