Hi on my new x570m Pro4 mainboard sometimes the network card is no longer present.
I solve this problem by cleaning cmos from jumper mainboard.

My configuration is as follows:
CPU Ryzen 7 3700x
Memory 2x16 G.Skill F4-3200C16-16GVK
AMD Radeon Pro WX2100
BIOS 1.90.

I've been using this mainboard for the last 4 months without any problem. Then yesterday this sh*t started and my Intel NIC adapter was not recognized anymore. I tried the PSU unplug thing but didn't work.

What worked for me:

- update BIOS to 2.50 (optional)

- reinstall Windows 10 and all drivers (optional)

- reset CMOS by removing the Battery for 10 Minutes (I don't have a cap for the CMOS Jumper)

After this everything seemed fine until this morning when I started my computer and my adapter was gone again! So basically it lasted yesterday for a few hours and today same problem. Actucally now it's working again!

That's what I did today:

- unplug PSU cable and switch the button from 1 to 0 waited a little bit and turned it on.
- also I switched some USB cables around

Now it's working again. I wonder for how long. I really hope ASrock can fix this issue soon with some driver updates. Also I suggest that we all submit tickets to ASrock to speed up this process. I already submitted a ticket.
