hey, i've seen that 0x80070570 error so many times building pcs. tbh, it's almost always the usb installer itself.
first thing i'd do is recreate the bootable usb. download the media creation tool again and make sure it's a fresh install. sometimes the usb gets corrupted or the creation process isn't quite right.
if that doesn't fix it, then yeah, could be ram. you can try running with just one stick if you have multiple.
