I'm sorry for your difficult hatching experience!

I don't dry hatch either and I actually do live in an extremely humid area and it still doesn't work for me. This is one of the huge differences I always try to explain to those that are using styrofoam vs plastic incubators. While location does play a role it really only makes a difference when you don't have the incubator inside a home with central air (or a pellet stove) drying everything out. I had a hygrometer outside of my incubators in the hatching room and it was usually around 45% humidity in the room, which would be great for early incubation if the heating elements weren't drying out the interior of the incubators even more. Note that in the same room under the same conditions I was able to run styrofoam incubators about 10% lower humidity at all times and had great hatches, so I'm convinced the material makes a difference.
(this is what it looks like inside my incubators with and without water when it's 45% ambient humidity in the room)

Type of incubator, where you're keeping your incubator, and how porous your eggs are, I really do believe are going to make the biggest determining factors for your humidity. Shrink wrapping isn't really a concern until after lockdown. During hatch I do always increase humidity to around 65%. You may find this works better for you.
Every hatch is a learning experience and it will get easier as you learn more about your personal set up. I'm glad it hasn't scared you off of hatching.

I hope your next hatch goes better and that you're able to find the sweet spot for your incubator!
