Is the issue specific to BIOS 5.69 or has it occurred on older versions too?

Try clearing CMOS then loading BIOS defaults. Once complete enter the OS and shut
down the system from there. Once this is done enter the BIOS and set whatever
settings you typically use.

Make sure you have the latest AMD chipset drivers installed.

An issue with your OS could potentially cause these symptoms too but if it was
working without issue and the only change is a BIOS update then I would open
a support ticket with ASRock and inquire with their Support staff:

I attempted to recreate your issue with my own x570 Taichi and a pair of RX 580s
but I wasn't able to reproduce it. I updated to 5.69 and installed all the drivers
etc but the system didn't exhibit the issue you describe. It may be because I don't
have the same additional hardware, I have a Ryzen 5 3600x in my Taichi at the moment
and I don't have an A750 to throw in. I am afraid that is about all I can do. I
am just the moderator here so I don't have access to the same kind of resources
as ASRock's Tech Support staff. I had hoped that the fact I coincidentally also
own an x570 Taichi would allow me to recreate the issue but no dice.

Good luck and let me know how it goes with ASRock's Tech Support department.

Shutdown, unplug GPU, unplug cmos battery, reset CMOS, plug the battery and GPU, Start system, still not detected, even in hidden device.

Restart in safe mode, DDU Driver and shutdown.

Turn On PC, Run Intel Driver as administrator.
Still not detected. Not Show up in Device manager.

Unplug A750, Change with RX470. Same, not detected in hidden device manager.
Unplug RX470 and B580, Change A750 to PCI e 1, not detected, hmmm funny..

For BIOS requests you will need to open a support ticket with ASRock Tech Support:

I am just a moderator, I try to help where I can but I am not ASRock Tech Support.
