Blaszok - Ultimate Multi-Purpose Responsive Theme

WPBakery Editor is not available at edit screen for product/post/portfolio.

First, make sure that you are using WPBakery Page Builder version shared by us in theme package or via Appearance->Install Plugins.

Please go to WPBakery Page Builder->Role Manager->Post Types, set it to "custom" and activate for needed post types/products etc.
Make sure to resave settings even if it showed correct post types enabled in first place.
