Hybrid is using Avisynth+ (32bit) and loading:
in Hybrid works fine.
If you installed a Avisynth+ 64bit version on your system, your script will not work with Hybrid since Hybrid only supports 32bit Avisynth.

Ps.: I can reproduce the issue with ImageSource which isn't part of Avisynth+, which is probably why Hybrid uses the ImageSeq-Filter and ImageReader.

LoadPlugin("I:\Hybrid\32bit\avisynthPlugins\ImageSeq.dll")

return last
