Cant add atributtes Woocommerce products

When i Try to add atributes to any Wocommerce product it goes loading forever. I’ve checked many forums and it seems it is related to WP Bakery Visual Composer. It seems that updating this addon could fix this problem, but we cant update it without Arcane update, so it is going nowhere.

Console shows such thing:
