I've tried installing the Arduino Adafruit playground but came across the same error.
sketch\src\Libraries\Adafruit_Circuit_Playground\utility\Adafruit_CPlay_LIS3DH.cpp:27:35: fatal error: Adafruit_CPlay_LIS3DH.h: No such file or directory #include <Adafruit_CPlay_LIS3DH.h> ^ compilation terminated. exit status 1
I don't really know what else I can try. I've tried reinstalling the library and different versions of the Arduino IDE but is doesn't seem to work.
IDE version: 1.8.7
Playground version: 1.8.1
