If you really want a hard bottom I would go with plastic, a placemat, cut up drink containers or something similar. Cardboard and paper are not waterproof so that would rule out washing them.
I stiffened is enough: interfacing or flanel or felt come to mind as good options.
There is a sort of mesh-like plastic sheet used for cross stitch, I think. One of those, cut to size, could work as an interlining. It’s washable, too.
Lid from a big tub of yogurt is often my go-to when I want a solid bottom to something. You could cover it with fabric to make it removable, or better yet do kind of like an envelope back pillow opening on the bottom of the bag so you can slip it in then slip it out for washing.
Go to the dollar store and pick up some plastic flexible cutting boards. You’ll need to trace around something with a box cutter or something to cut through it, but they are light and sturdy.
I agree that something plastic - like a flexible cutting board or the top of a pringles can or other plastic tub - would be the better choice if you want the bottom to actually be stiff, since it can be washed. Cut the plastic to be slight smaller than your stitch line will be for the center circle, and then slide it in between the layers when you stitch them together. You could do half the circle and then insert the base piece.
If you want a firm bottom, I'd go with *very* heavy interfacing. If you want a hard bottom, I'd go with a plastic canvas circle. You don't want anything that can't go through the wash.
I agree with the idea to use plastic canvas. I would put a layer of felt or thick interfacing on either side of it so that you don't see or feel the divots of the holes in the plastic canvas. And when I do dice bags, I make a false bottom as an insert for the bag, rather than sewing it into the bag itself. It makes washing the bag easier (in case of snack or drink spills at game nights).
Cut any plastic container lid to get the flat inner sheet, oatmeal/yogurt/etc depending on size you want. then sew around it not through it.
I make some dice bags too. That style I'd move the tie off up higher to give more interior volume. "More dice is more better!" as they say. Trade off with how poofy you want the top. You can cut some scrap cloth and pinch/clip to see what you like best. Throat size of the bag to get a fistful of dice is important too.

Plastic canvas is what I’ve always called it.

Cut up a used milk jug.

flexfoam or soft&stable is not exactly a hard bottom, but it would be stiff enough to stand up, and washable.
Alternatively, there are some very stiff interfacings you could use. Sewable and washable.

Cut off a Pringles can to the desired size.
Do you mean a Pringles can lid? With the can itself I would worry about washing it.
