NsightEE -- eclipse sith the nsight plugin problem on CUDA 11.2

I upgraded from CUDA 10,1 to 11.2 on Linux, and apprently nsight eclipse edition is now discontinued in this version. So I installed the nsight plugins on my eclipse
But now when I try to open or recreate a cuda project on eclipse I am getting the following error:

    An internal error occurred during: "C/C++ Indexer".
org.eclipse.cdt.internal.core.dom.parser.ASTTranslationUnit.setupBuiltinBindings(Lorg/eclipse/cdt/core/dom/parser/IBuiltinBindingsProvider;)V

Please help,

thanks
