Additional information & file uploads

The problem is in configuration.h where the #define INVERT_Z_DIR is true instead of false. Please, change it to false before compile. This will solve the inverted movement on z axis.

From Creality configuration files (works in Ender3V2 with 4.2.2 and 4.2.7 boards):

// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR false
#define INVERT_Y_DIR false
#define INVERT_Z_DIR true
