Skin is not loading (ESX)

When I create my Character and select the Basic informations like the Name etc. I don’t get the skin menu to chose my Appearance. So I’m invisible and when I type /skin as an admin the skin menu doesn’t open. Does anyone knows a solution and can help me?
(The framework is ESX)

Hey do you have the resource “skinchanger”. If not then that could be the problem.
