registering new tab in settings panel not works #2

Dear @timmydcrawford, @apmwebdev!

(See previus topic: https://wordpress.org/support/topic/registering-new-tab-in-settings-panel-not-works/)

Sorry for the late reply, but I was on a short vacation. The error still exists. The WordPress environment contains only the necessary plugins, as I use this environment for development purposes only. I’m new in developing plugin for WordPress and in specially for WooCommerce and maybe there is a stupid error in my code, but I can not figure out where. My code was working before version 0.24 of the Woocommerce Admin.

See my WordPress health report:
