New Puppy Issues

I just adopted a 4 month old puppy. Whenever we leave her in her crate she will aggressively paw at the door and bite the wires in attempt to escape. She will destroy any toys or beds that are in there with her. She whines and yelps. We set up a camera to keep an eye on her while away and saw this can go on for hours. She will do the same thing at night in her crate which is in our bedroom. I had to order a new heavy duty crate so she cannot escape or hurt herself while we are gone. I’m not sure if this is because she is still adjusting or she may have separation anxiety. I also don’t know if she just hates closed doors in federal because I will take her into the bathroom with me so she can’t get into things while I’m not looking and she will still whine and paw at the door when we are in the same room. Any thoughts or advice would be appreciated.
