Preheat the oven to 350°F. Bake the pie crust according to package instructions until golden brown. Allow it to cool completely.
In a mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until well combined.
Spread the cream cheese mixture evenly over the cooled pie crust.
Arrange the mixed fresh berries on top of the cream cheese layer in a decorative pattern.
In a small saucepan, heat the apricot jam and water over low heat until melted and smooth. Brush the mixture over the berries to give them a glossy finish.
Chill the tart in the refrigerator for at least 1 hour before serving.
