Failed To Load Resource: The Server Responded With A Status Of 401 (Unauthorised)

I have Visualforce pages contains Lightning App, that contains Aura components hosted to Community aka Experience Builder, which are working fine when user is loggedIn, however, for guest users it is throwing "Failed to load resource: the server responded with a status of 401 (Unauthorised)" Please find the below code for the VF page and controller class

 [removed] // Here 'VfApp' Is Lightning Application Name $Lightning.use("c:UserActionMenuApp", function () { $Lightning.createComponent("c:horizontalNav", { }, "horizontalNav", function (component) { console.log("component created"); }); }); [removed]  
Code for the Class file
