Just two comments:

  - Your post suggests you're calling .Internal() yourself, but that's 
not the case.  So your question should be about why eigen() crashes R.

  - If you need a long script to trigger the error, I'd assume there's 
something wrong in that script. Your script uses several contributed 
packages, so the problem could be there. Shorten it to a minimal 
reproducible example that doesn't use any contributed packages.  If you 
can't leave out the packages, try to reduce it to just one, and ask the 
maintainer of that package about it.
