Broken, What Happened? No output – BIAS FX - Guitar Amp & Effects Review

This app worked perfectly ever since I bought it but for the last three days it has not been outputting ANY sound. I know everything is being inputted correctly because the tuner works, and whenever I switch between presets, it’ll make a sound of audio (I strum while I switch to be sure) but when it’s done loading it’s silent again. It’s also not working with Inter App audio at all. I tried uninstalling and reinstalling but it’s just broken.
