Hello, I'm an ignorant coder, I made a buttonbox project only the code I did not work I installed the keypad and joystick libraries and now I have another message and I do not know what to do, can you help me this would be greatly appreciated. here is the error message: Compilation options have been changed, everything will be recompiled C: \ Program Files \ WindowsApps \ ArduinoLLC.ArduinoIDE\_1.8.15.0\_x86\_\_mdqgnx93n4wtt \ Hardware \ Arduino \ Apr \ Cores \ Arduino \ CDC.cpp: In member function 'available': C: \ Program Files \ WindowsApps \ ArduinoLLC.ArduinoIDE\_1.8.15.0\_x86\_\_mdqgnx93n4wtt \ Hardware \ Arduino \ Apr \ Cores \ Arduino \ CDC.cpp: 187: 1: Internal Compiler Error: Segmentation Fault } ^ Please submit a full bug report, with preprocessed source if appropriate.

- When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21". - Click "Install". - Wait for installation to finish. - Click "Close". Due to a [bug](https://github.com/arduino/Arduino/issues/7973), this workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE. If you have **File \> Preferences \> Check for updates on startup** checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again. ---
