Garageband outputting no volume

Hi. I’ve been trying to use GarageBand but it outputs no volume whatsoever for the songs and instruments. As far as I can recall, it’s been like this since iOS 18 was released, but I feel like this big of a bug would’ve been fixed by now, so I doubt it’s that. I have reset GarageBand multiple times as well as deleting and redownloading it. I genuinely have no idea at all what’s wrong with it, and if you could be of any help at all, that would be great. Thanks in advance.
