Heres my script when i press “e” it doesnt unlocks the cursor.

if(Input.GetKeyUp("e")) 
  {
    if(InventoryShow == false)
    {
      Screen.showCursor = true;
    }
}

When i press “e” the GUI shows up but the cursor locks.

You can try adding Screen.lockCursor = false; to your script. Unity - Scripting API: Screen.lockCursor
