Certain games use a system that holds the mouse cursor in place, and instead uses the relative mouse movement, rather than the absolute cursor position, to drive the ingame cursor.
Cyberpunk 2077 uses this system, which means it is not possible to position the mouse cursor using absolute coordinates (because the game does not use them for its input system).
You may be able to get the ingame cursor to move by using the "Adjust the Mouse Cursor Location" section of the mouse move action, and checking the "Move using relative data (useful for 3D games)" option
To attempt to move to a given point on screen, you can try first moving the mouse cursor to a corner of the screen (E.G. the upper left corner) as a home/reference location, and then moving a given distance from that position until you reach the desired position.
Note that if the game applies (positive or negative) mouse acceleration, this can effect the positioning accuracy, especially if the game's input system is affected by ingame framerate.
