I don’t think there are any bedroom-sized dehumidifiers that will be quiet enough to use at night.

These are super quiet actually, for a bedroom you just need a very small one.

When you say 69, that's at the thermostat right? You need to measure the temp in your room also.

For best humidity control you want your HVAC running almost constantly during the summer. This means its proper sized and running often pulls the most amount of moiusture.

Given that, as said already you also likely have a bad air leak situation from the crawlspace, windows, etc. that's letting in moist outside air.

If this is an older home many of them also have very poor return air vents or usually none at all. So you may be getting cold air vented IN but no air pulled OUT. So you just have cold wet air in your room. You need to have a space under your door or even better return air vent to your unit for best results.

ETA: FWIW when most people say they like it cold to sleep they mean they like it low humidity. They turn the air colder to remove humidity, but the cold air is just a secondary benefit.
