Possible typo Crashing Temporal filter.

[Wisperer]

Okay I've stabbed at it some more. I went back through and re did my script comparisons. I made sure exactly EVERYTHING was the same.

This line at the end of the debug .VPY caught my attention. 

stacked = core.std.StackHorizontal([original,clip])
# set output frame rate to 23.976fps
stacked = core.std.AssumeFPS(clip=stacked, fpsnum=24000, fpsden=1001)
# Output
stacked.set_output()

it's not in the older 2020.12.13.1 stable build.

in that it looks like 

clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="limited")
# set output frame rate to 23.976fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=24000, fpsden=1001)
# Output
clip.set_output()

 I added the  scripts as attachments again.
