Flyweight
Imagine you are developing a video game inspired by the popular anime "Konosuba". In this game, players control multiple main characters like Kazuma, Aqua, Darkness, and Megumin. As your game gains more popularity you decide to add new characters and enemies like Yun yun, Eris, Wiz, etc. When you release this new update you start receiving too many tickets from the users saying that the game stopped working or that it just crashed.
