Visual Composer doesn´t load when WooCommerce Page Builder is activated

Yesterday I downloaded the WooCommerce Page Builder and since it is active my visual Composer shows me a white Screen and it tries to load forever, but nothing happens.
When turning the plugin of it works.

already found that it has to do with the plugin, but getting crazy here.
I appreciate any ideas! Thanks

My Woocommerce Version 2.6.4
Visual Composer 4.12
WordPress 4.5.3
