Problem launching new DLC (Forza Horizon 5)

After installing the new DLC, absolutely nothing happened to the game. When I go to start the test, a cut-scene passes and offers to install, even though everything is installed. If you open the map through the menu, it throws out a menu for the purchase and itself claims that the add-on was purchased. I have the game in the premium edition, bought in the Microsoft store. if you know the solution, please help.
