Export Toolkit Bundle - Attempted to load class “COM” from the global namespace

Hello

I have install “Export Toolkit Bundle” plugin in my project(v.6.6.5 - windows OS) and set all configuration, now i go to export toolkit tab and select class and set attributes which i need to export in csv format, so i clicked on Start Exports button then i got this error “Attempted to load class “COM” from the global namespace. Did you forget a “use” statement?”.

Before of this i have use this plugin in other project(v.6.5.3 - Linux OS) and this is working fine.

Anyone have idea why getting this error.
