The error says:
looking at: https://github.com/Selur/VapoursynthScri...avsfunc.py
line 2781 does not call DFTTest.
In the havsfunc.py for Hybrid, line 3141 contains:
The dev version I send you (line the normal package), comes with a vsscripts folders which is a checkout of the git (https://github.com/Selur/VapoursynthScriptsInHybrid/).
The script you use seems to differ.
So my guess is that this isn't a bug in Hybrid, but you using old, new or simply other script versions than Hybrid.
I suspect that copying the content of the vsfolder (the git) into your site-packages folder will fix the issue.
Alternatively delete the script files inside your site-packages folder, since Hybrid explicitly adds it's script folder to the Vapoursynth search path.
