Error creating an Udon program "UnityException: Creating asset at path failed."

I’m new in creating worlds for VRChat, and I have a problem that I don’t know how to solve. When I try to create a New Program with Udon for my world, it appears and error, it says: “UnityException: Creating asset at path failed.
VRC.Udon.Editor.UdonBehaviourEditor.CreateUdonProgramSourceAsset (System.Type newProgramType, System.String displayName, UnityEngine.SceneManagement.Scene scene, System.String udonBehaviourName) (at Assets/Udon/Editor/UdonBehaviourEditor.cs:183)
VRC.Udon.Editor.UdonBehaviourEditor.OnInspectorGUI () (at Assets/Udon/Editor/UdonBehaviourEditor.cs:107)
UnityEditor.UIElements.InspectorElement+<>c__DisplayClass58_0.b__0 () (at :0)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)”
Do anyone knows what could be happening? Thanks for your attention!
