cant package when using plugin

I am using marketplace blueman ai plugin. when i package i got 0 errors but still strange error, and packaging failed: screenshot attached where should find solution??

See here, How may I resolve an error "Couldn't find target rules file for target 'ProjectName' when building a project? - Programming & Scripting - Unreal Engine Forums , see if you have that Enterprise:True key somewhere in either your *.Target.cs, or the Plugins.
