Movie about girl that stays with a family friend and calls her dad periodically to check in - Coming of Age on HBO MAX

I honestly don’t remember much about this movie, but I do remember very small details.

The dad of the family she movies in with tries to get her to come out of the room, but she’s usually journaling or listening to music

There’s a soft brown lighting in her room.

One night she leaves the room and hangs out in the backyard with the dad and his kid, there is a small treehouse in the backyard, the mom of the family doesn’t like her there. She has a beer that night (I think).

The lead woman is white with brown hair, the dad has a stubble/beard?

Please help! I can’t find this movie on HBO Max anymore since the app moved to MAX.
