I'll fix this today.
Please add your VST plug-ins one by one until this is solved.
To be honest it is dangerous to open .dll files in the application. Other DAWs scan VST plug-ins in a separate process so that foreign code don't jeopardize the stability of the main application. This is not yet solved in RapidComposer.
Thanks for reporting this issue!
