Windows 10: ACPI BIOS errors 4 and 5 on shutdown

I'm running a year-old HP Envy desktop, with W10 Pro 1809. I am seeing these ACPI read/write errors (AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0x75), which lies in the 0x74 - 0x76 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.") logged in the Event Viewer, but only sporadically, and they ALWAYS occur on shutdown. I'm not sure when they started.


The system is otherwise OK (touch wood), and I really want to know what is causing them. The "system vendor" seems to have absolutely no idea.


I am running the penultimate BIOS F.22 for this machine. There is a BIOS update to F.30 which is described as " -The first 19H1 softroll production BIOS". 19H1 is, I understand, W10 1903, which I'm not running, and I can't see how an update for a future W10 64 bit 1903 OS instal will cure problems on 1809.


I have checked all drivers possible and updated them. Someone, somewhere, must have some idea of what causes these, and what possible solutions there are, and I don't want to start possibly futile or damaging "on a hunch" remedial steps.

ACPI Bios Error

A friend of mine built his first computer and iv been called in to figure out what in the world this problem hes having is. Iv tried quite a lot already, ill list those out in a second. He never got past trying to install windows 10 due to the ACPI BIOS
ERROR.

System spec:

AMD Ryzen 5 2600x CPU

ASUS Prime B450M-A Mother Board

Strix GTX1050ti GPU

Ballistix DDR4 2600 RAM

a 2Tb Western Digital HDD

Behavior on boot attempt: The computer starts up fine, gets to the ASUS logo screen and then BSODs with the ACPI BIOS ERROR.

I have tried:

updating the BIOS

clearing the CMOS

tried installing Win7 same Error

Installing Win10 on the HDD outside the system.

Using Rufus to make a bootable USB from the ISO files

CSM, Secure boot, Fast boot, all OFF/ON in every variation

SATA switch to RAID from AHCI

IV tested all the hardware plus gotten Linux to run fine.

After all that the only change is that now it tries to boot into the automatic repair after the first 2 BSODs but the moment it tries to load its just BSODs with the same ACPI BIOS ERROR.

Not gonna lie im pretty stumped on this one, best guess is its a windows 10 problem somewhere. Judging from google i'm not expecting an easy one click solution but any help would be appreciated.
