You are feeding her 3times a day every other day? And she is eating?

Anyhow, no judgement here, lets do what needs to be done now.
how are you feeding her, tongs? Or just dropping food in front of her?

First of all, they dont overfeed, they dont eat more then they can handle, however food need to be healthy, pretty much like for people, burger/fries diet vs healthy diet.
You need to forget about mealworms and superworms, both are fattening, as well as Eli mentioned already, they are high in chitin component that frogs cant digest, feeding those can lead to impaction.
crickets are very poor feeder too, they provide very little nutrition and are not enough for an adult frog.

Get nightcrawlers from any bait stores, make sure they are not dyed, although I've never seen dyed nightcrawlers myself, I've head they do exist. Nightcrawlers are by far the best food for pacman frogs, easy to digest, they have the best P:Ca ration for them too. You can also feed dubia.

She looks perfectly healthy, at her size she should be hungry 2x3times a week. You can do a warm bath for her to help her poop, you can add a few drops of honey to your water, but make sure the water level is no higher then frogs chin. Keep her in therefor about 20 min and then replace honey water with regular dechlor water also warm for another 20 min. During these bath you can very very gently massage that hard lump on a left side.
