Crate during the day in an apartment

Hello!

I just got a puppy (5mo) on Jan 14/26 in the evening and she was kennel trained at her foster house prior to me adopting her. Since then she whines and barks like crazy in her kennel, I have tried covering it, creating a positive association with it, and starting with small successes.

Today when I left for work I put her in with toys, treats, and a frozen lick mat but when I had somebody come to check on her 1.5hours in, she was still crying and barking.

I live in an apartment (I have notified my neighbours already so they are aware and hopefully will have a bit more patience with me), but she cannot keep barking in an apartment.

Does anyone else have any ideas and experience with this?
