Problems after X470 Master SLI AC BIOS 3.30

Good afternoon everyone,

Yesterday, I upgraded my BIOS of my X470 Master SLI A/C to the latest version, 3.30, which went on without a hitch, but after flashing, the BIOS restarted twice before booting into my loader for Windows and Linux, which it's never done before after previous BIOS updates. Now, any time I power down my computer and cut power, I have to clear my CMOS or else the POST gets frozen at code A0. So I clear the CMOS and reboot, and everything is fine until the power is cut off (the computer reboots fine as long as it's just restarted.) Does anybody know what's going on? I even tried re-flashing 3.30, which made no difference. I'm stuck clearing my CMOS every time I shut off my computer.

Any help is appreciated, thanks.

Does it appear after shutdown with Windows and Linux too?

BTW: A0 - IDE initialization is started

So my main drive is an M.2 SSD, I also have a SATA SSD and a SATA hard drive, the latter of which I tried disconnecting with no luck (it still freezes at A0). The only way to power down once it freezes is by holding the power button until it shuts off, as it's totally unresponsive. Once I clear the CMOS, it starts up, reboots at POST, and then POSTS again and I can get into my loader (which is on the M.2 SSD), which never happened before the 3.30 update.
