Green vertical line on left side of the screen after filtering in Avisynth?

Hi.

Somehow this is what is appearing when I filter certain videos and cropping doesn't remove it. It's not there originally anyway. What is it and how to remove it? Here is an example of a video I just uploaded and you can see this thin line on the left side of the video

And here is the script:

AviSource("input video", audio=false)
ConvertToYV12(matrix="PC.709", interlaced=false)
Crop(2,12,-26,-12)
CNR2(un=100, vn=100)
CNR2(un=100, vn=100)
Dehalo_alpha(rx=4, ry=1)
TemporalDegrain(SAD1=200, SAD2=150, sigma=8)
nnedi3_rpow2(2, cshift="Spline36Resize")
aWarpSharp(depth=5)
Sharpen(0.2, 0.0)
nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1440, fheight=1080)
aWarpSharp(depth=5)
Sharpen(0.2, 0.0)

awarpsharp is the culprit, try awarpsharp2 instead
