American Toad is constantly eating substrate and becoming impacted, what to do?

Probably due to some other type of problem, have you been dusting her food lately? What I'd do for now is make a setup that is just dry or damp paper towel, so there's no risk of any more impactions. Also, try feeding Canadian night-crawlers if you aren't already, they're easy to digest, very nutritious, and can be hand fed, making sure that no substrate gets in the toad

I would try regular Dirt, Something that is hard and can be packed down. When I mean hard I mean like clay dirt or something, something she can't dig up and eat. (If you do that, make sure you have plenty of places to hide. So she doesn't get to stressed out.) It might seem hard or mean because she is a toad and should be able to dig, but if she is harming herself and making herself this bloated, it might be the best we can do for her.
How humid is your tank? Do you have a bowl in her tank for her to soak in?

Maybe paper towels would work, like one would do for a quarantine setup? Its not pretty and you'd have to replace it often for mold but everything else sounds too edible.

EDIT: okay clearly my critical reading skills need work. I skipped the last part accidentally. Though putting her outside would probably kill her because if her dirt eating isn't husbandry related, what will stop her from doing it in the wild with no one to soak her? This is really a tough one, sorry its happening to you.

I think like I said before, the best thing to do for her is to place her on paper towels, so you can be sure she doesn't eat any substrate
