Solved SIGKILL sent by diskarbitration during install (offline and online)

[CaMo3BaH4uK]

Hello. I am trying to install big sur on my computer. I did the OpenCore 0.6.5 setup using the Dortania guide. I keep getting the error "SIGKILL sent by diskarbitration" during the installation at 12 minutes mark. I tried to install from USB stick, HFS partition on disk and direct upgrade from 10.15.7. All is unsuccessful.
Here are the specifications of the computer:

Spoiler: specs

CPU: AMD Ryzen 7 2700X
RAM: AMD Radeon R7 Performance Series 8 Gb * 4 sticks
Motherboard: MSI X470 gaming pro
GPU1: NVIDIA GeForce RTX 2060
GPU2 (For macOS): NVIDIA GeForce GT 740
SSD (For macOS): Smartbuy Stream E13T

Also I am attaching the OpenCore config

This config works fine on 10.15.7
What could be the reason for this error?
Thanks in advance for your help

What happens if you leave it? Normally that shouldn't halt the install. Can you share the full installer log please.

Hi. If I leave it, then I will have a completely empty APFS volume after reboot, and when booting from USB, I will again download the installer image from the servers. I have successfully installed big sur using opencore setup from this thread. After installation i use my opencore config.
