Pouching and not stashing!

[Cujo]

Jasmine has been pouching ALL of her food and will NOT drop or stash it at all. Period. Im worried about her injuring herself, or worse. Ive done a complete cage clean upon noticing this behavior to eliminate the possibility of her not being satisfied concerning the cleanliness of an area being suitable to stash, but to no avail. Ive tried adding more bedding, my next option would be to downsize her bin to a cage, shes in a LARGE diy bin cage. Its to the point now where she sleeps with cheek pouches full. I cant imagine this is comfortable for her, and dont want her to feel anxious or stressed. Tips?

Cleaning the cage could make it worse if she feels there isn't anywhere safe to stash her food so I wouldn't change anything at all for a while.
How long has she been doing & did anything change around the time it started?
Have you checked to make sure her pouches haven't become impacted? Both would be unusual but sometimes they do get things stuck in them that they can't get out or have other problems with their pouches.
