Dehumidifier and AC is a massive waste of power and generally doesnt do anything

If there is any humidity built up in the room, running it could be a defense if damage is argued by their landlord.

Also, I highly doubt even if the intake vent were open that it would successfully pull a significant amount of hot air in and cause humidity damage at any meaningful rate in OP's climate in California.

I'm on the side of letting people keep their windows open, as long as there isn't damage. If the landlord is afraid of damage, they can raise their concerns and work with OP to formulate solutions instead of physically shutting their window from the outside and escalating this the way they did.

    I'm the last person to support landlords, but a dehumidifier is essentially a heat pump, whereas an ac is a heat pump in reverse - both arent 100% efficient though, and so are using power to remove heat, then power to create heat is at best wasted power.

    That being said I can't imagine op would even be able to survive with a heat pump warming their place in this weather anyways.

    Sucks for the landlord's power bill, but the people who commented here can do better. Sorry to lump you in with them. I wouldn't want a landlord micromanaging my window use by shutting it themselves and demanding I keep it shut, especially if I had some valid reasons.

    I suggested a dehumidifier because damage/mold was brought up, definitely wouldn't be very viable as you suggest (especially in regards to temperature). Thanks for keeping it grounded and fair, and you are right that hot air would be pulled in, but I'm not too sure about that having a major effect to the point of very expensive damage or major effects on power, especially if OP's door is shut and considering other factors, such as climate, room size, and it being a single window.

    Some of the arguments here in the larger thread do make sense, pulling in hot air and another commenter suggesting that it would cause an effect across the house, pulling outside air from other cracks and openings and increasing humidity/temp throughout the building, but I feel that the effect on the house/system is minimal if it's a single window in a small room.

    I have a weather app (Breezy Weather) that shows me a humidity graph, that could be helpful for OP if they are reading this.
