That curdling is intentional in the class method: vinegar is mixed with milk and rested to make an acidified milk mixture. The acid also matters where baking soda is part of the recipe.

That's different from a butter batter splitting because cold liquid was added too fast. Follow the recipe's mixing order and use compatible ingredient temperatures for the creaming stage.
