Lab puppy doesn’t like crate anymore

My lab puppy is almost 4 months old and was doing great in the crate . No accidents , took naps on it , sleeps at night and barks only to go out to pee. Now all of a sudden she doesn’t like it . She barks and won’t stop . I wait until she stops praise her or take her out to go pee put her back to enforce sleeping . I’ve used treats still doesn’t want to be in it . She gets plenty of exercise . I run her in yard with my golden retriever , play , run her again . She’s definitely over stimulated but won’t go to sleep ! Help need advice . I’m exhausted .
