I've never done it myself so YMMV but was near a friend who was attempting to restore files on a 10 yo USB as well.
First off - EaseUS can only recover 2GB for free, you have almost 3 GB selected here, my friend ran into the same problem.
He ended up using another tool called Puran or something, I'll see if I can find it.
EDIT: Found it (you need an account to see links)
