Game crashes after hotfix

Thanks.
The bios is set with one of gigabyte preset oc modes. Though I have capped the vcore voltage to 1.38v.
To prevent the wild vcore voltages that auto provides.
They pc has been 100 percent stable, in every single application , and has never gone over 83 degrees on two cores only, under high stress test. I am using an aio 360 water cooler, with a massive Thermaltake x71 case.
But I suppose that I could load bios defaults and try it again. It wouldn’t hurt.
I upgraded to Windows 11 through Microsoft.
I really don’t fancy re installing through an iso image, and having to go the the hassle of putting everything back on to a fresh install.
Not for the sake of flight simulator 2020.
Not when absolutely everything else works absolutely flawless.
Graphics card is not overclocked.
