Since https://github.com/AmusementClub/VapourSynth-FFT3DFilter has the reporting of issues disabled.
I thought I post here that R2.AC3 seems to be broken on older CPUs like the i7-3630QM.
Background: I got a user who was complaining the QTGMC in Hybrid (https://forum.selur.net/thread-3110.html) didn't work for him.
After some testing the conclusion was that:
a. fft3dfilter was the culprit of causing Vapoursynth to simply crash without an error.
b. R2.AC3 didn't work, but neo-fft3d (https://github.com/HomeOfAviSynthPlusEvolution/neo_FFT3D) and myrsloiks fft3dfilter (https://github.com/myrsloik/VapourSynth-FFT3DFilter) both work for him.

So, if anyone with an older CPU runs into Vapoursynth crashing without an error message, trying an older fft3dfilter version might help.

This release only requires AVX support. Please note that AmusementClub's internal forks require AVX2 support in general.

Thanks!

Maybe add that info to https://github.com/AmusementClub/VapourSynth-FFT3DFilter/blob/mod/doc/fft3dfilter.md other users have a change to know that. :)

Ehmm,... vs-fft3dfilter-windows-R2.AC3-AVX.7z from https://github.com/AmusementClub/VapourSynth-FFT3DFilter/releases/tag/R2.AC3-AVX only contains an empty folder,.. ;)
=> fixed
