A Hybrid user reported this issue to me and I can reproduce it on my system.
using https://github.com/EleonoreMizo/fmtc...leases/tag/r22

it randomly crashes,... every few times,..
Changing the source filter from LWLibavSource to FFMS2

core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/SourceFilter/FFMS2/ffms2.dll")
clip = core.ffms2.Source(source="F:/TestClips&Co/files/YUV/yuv422_16bitBitEndianStereo.mov",cachefile="E:/Temp/mov_f1203bb1621d87009c15418dab3b00fb_853323747.ffindex",format=vs.YUV422P8,alpha=False)

doesn't help, it even seems that it crashed more often with ffms2.

removing:

clip = core.fmtc.resample(clip=clip, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)
original = core.fmtc.resample(clip=original, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)

and everything works.
Changing "spline16" to "spline64" same thing happens, but it seems to happen less frequently.
(same for spline36)
When using 'cubic' is seems to always crash.
