The `win` you're creating in `init` is a function-local variable. It ceases to exist when `init` returns. It's not `this.win`.In `run`, you're accessing `this.win`. It's still null because you never assigned anything there.So change `auto win = ...;` to `this.win = ...;` or simply `win = ...;`.
oops, I forgot... haha what a silly mistake, thank you
