Patience, it is a puppy thing and she will grow out of it. Caesar did and I never thought I would see the day when he wasn't a little terror. I agree with opening the crate door. And close the bedroom door so she can't escape. You don't want the crate to seem like a punishment. And a good tiresome evening walk is a good idea. We're going through this with our German Shepherd X. By 7pm she is literally bouncing so I take her out for a good run and she comes home and sleeps. Hang in there, and good luck!
