Run a dehumidifier like others have said. For windows I don’t need to use in the winter, I use this 3m insulating plastic that covers them. It’s like cling wrap that covers your windows. It helps keep my house better insulated and seems to keep what you’re describing from happening. You have to make sure it’s sealed really well and you won’t be using that window all winter, though.
