Is there anything at all that may have scared or startled her while in or near the crate?
Maybe she has grown some & the crate is now uncomfortable?

I know you wanted her in the crate but actually picking her up & placing her in the crate was a no-no. I'm surprised that after that she willingly went in the crate today.

Anyways, i would start all over again, just like you would a puppy making the crate a happy place only. Feed her in it, leave her in the for short periods of time but often. Give her extra special treats & toys in there.
good luck
