Error code 0xC0000005 is Access Violation.
Perhaps other members might be more inclined to answer if the gobble-de-gook was translated into the forum language, ie English.

Convolution3D is an old filter, it was written in 2002 for avisynth 2.0.

The latest version available is a beta, released in 2003, 15 years ago!, for avisynth 2.5, with no temporal processing and some problems (http://web.archive.org/web/20111205204423/http://hellninjacommando.com/con3d/beta/readme.html).

You can use better 3D denoising filters like fft3Dfilter, DFTtest, or much better MDegrain[n] included in mvtools.
