Problems with Compiling WriteInstinct

This is my first attempt of compiling something in the Arduino environment, so a lot of obvious things aren't that obvious to me.

So after hopefully installing all the right libraries, I get a lot of errors of the kind shown below:

C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.55.0_x86__mdqgnx93n4wtt\libraries\Adafruit_Circuit_Playground\Adafruit_CircuitPlayground.cpp: In member function 'void Adafruit_CircuitPlayground::playTone(uint16_t, uint16_t, bool)':

Error compiling for board Arduino Uno.

Any ideas would be highly appreciated.
