Since this rom is trying to emulate Pixel, the only "gallery app" that will ever ship by default is Google Photos. And there's nothing we can do to fix the usb issue, we'll have to wait for an update to fix it. You can try using FTP to wirelessly transfer stuff in the meantime.
there is also no gallery option and also the major problem is usb please do help
