1, "USB:SONY"
2, "UEIF : SONY , partition 1"
3, "NVME"
------
1,so, when I select "USB:SONY" I am getting windows logo but no circle loader (screen is stuck here).

2,so when I select "UEIF:SONY, partition 1" I am getting "ASrock" logo on my screen and (screen is stuck here).

Could be your flash drive is not bootable. I have a B550 Phantom Gaming 4 MB and a Sony 32GB USB flash drive.
Go here: https://www.microsoft.com/en-us/software-download/windows10
Under Create Windows 10 installation media download the Media Creation Tool20H2.exe
Use it to create a bootable USB flash. It will format your flash drive to Fat32.
In the bios screen chose USB: Sony Storage Media 0100 as your first boot drive.
Be sure to Save before rebooting.

I have used https://www.microsoft.com/en-us/software-download/windows10 to create my bootable Pendrive already. If I select "USB: sony" I am getting the windows logo and the screen is stuck there. Also to verify my bootable Pendrive I have used my laptop to boot from that Pendrive and it worked fine. (Also to check whether my system components are working properly I installed Ubuntu in my system and it is working fine even detecting RTX3070 graphic card).
