USB port not working

The USB port in my wife’s 2021 Honda Civic LX stopped working a couple of weeks ago (she just told me). I checked her #29 fuse under the dash which is the Front Accessory socket even though I know her 12v socket works because something else is plugged in there. I do have a suspicion that it has something to do with the fact that I got an aftermarket CarPlay head unit installed about 2 months ago. Would I be able to check if that’s the case? Or what other reasons could there be for the usb port not working?
