On my old Laptop with Windows 10 (19045.6456 <- same you mentioned) and a i5-4200U CPU Hybrid and vsViewer works fine.
Here another user had the problem that Hybrid didn't work because his Windows version was too old.
Since it's the vapoursynth.dll that is crashing, it probably isn't a problem with Hybrid itself.
Looking at the changelog of 2025.07.27.1, first thing it states is "Vapoursynth: changed to Vapoursynth R72".
So maybe replacing the Vapoursynth files with files from an older portable Vapoursynth version helps,...
https://github.com/vapoursynth/vapoursynth/releases
afaik there should be no avx2 requirement for Vapoursynth with R72 (not sure about R73 which I will switch to at the end of the year).
(Nope, R73 is the final Windows 7 release, so that probably isn't the issue either)
