macbook pro mid 2012 13" upgrad with OpenCore does not work as well as it is expected / need help

Which MacOS is stable enough to run on my Macbook, 2.5 Ghz i5 with SSD and 16GB RAM?

I did some youtube tutorials on updating to Ventura but it did not go as advertised, did it several times, always the same result, when I boot from the USB stick there is always a white screen and this 🚫, icon,

Can anyone tell me what I am doing wrong?
