This code is exactly what was in the lesson on YouTube, where the cube moved up and down, but for me it does not move with the same button setting.Unity 6000.0.44f1

• Is your script/component attached to your player object? Are you getting any errors? Is the moveDirection correctly set in the inspector? – derHugo Commented yesterday
• Yes, I have the script connected to the object, the code was the same as in the video, there were errors – dreaming002 Commented yesterday
• InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings. UnityEngine.Input.GetKey (UnityEngine.KeyCode key) (at <cdfd6fe7d7e24e6f89b104f2abe4a286>:0) Player.FixedUpdate () (at Assets/Player2.cs:13) – dreaming002 Commented yesterday
• There you go ... the error sounds quite self-explanatory to me. => Go to Player Settings and change the input system setting to either use the legacy Input class or both ... or change your code to properly use the new Input System ... see docs.unity3d/Manual/Input.html and docs.unity3d/Manual/… -> Active Input Handling – derHugo Commented yesterday
• Thanks for the help, I'll try to figure it out. – dreaming002 Commented yesterday

(For quite a while by now) the Input class is legacy and there is a "new" Input System instead (see Input).

In newer Unity version also the default setting will be using only the new Input System.

=> You should start using the Input System instead as well.

If for some reason you rather want to stick to the legacy Input class (imho a valid reason is for example rapid prototyping where a full Input System adaption might be a bit overkill) you have to modify the according setting in Player Settings -> Other -> Configuration -> Active Input Handling

Choose how to handle input from users.
Input Manager (Old) => Uses the traditional Input settings.
Input System Package (New) => Uses the Input system. This option requires you to install the InputSystem package.
Both => Use both systems.
