Error compiling for board Arduino Uno R3

[emanmostafa24]

This is my first time to use
MPU9250 module with Arduino Tutorials -Accelerometer, gyroscope and Magnetometer sensor
Every time the same error message appears, what is the problem or what should I do?
Arduino type: UNO R3
Arduino: 1.8.19 (Windows Store 1.8.57.0) (Windows 10), Board: "Arduino Uno

avr-g++: error: device-specs/specs-atmega328p: No such file or directory

exit status 1

Error compiling for board Arduino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Here is a related issue with a couple of suggestions.

avr-g++: error: device-specs/specs-atmega328p: No such file or directory

Hi @svem-dir. Do this: Start Windows Control Panel. Navigate to System and Security > System > Advanced system settings. Click the "Advanced" tab. Click the "Environment variables..." button. In the "System Variables" list, you should see "GCC EXEC PREFIX". Click on it. Click the "Delete" button. Click the "OK" button. The error should now be fixed. [image]

Error message :Board at COM3 is not available"
The port part appears only when the Arduino is connected, which is COM3
