in thread CSV_XS ERROR: 2027 - EIQ - Quoted field not terminated @ pos 408

Based on the sample data you showed, it looks like the error is right after "vv11" -- here's how it looks, one character at a time (which is how Text::CSV has to look at it):
" # start of quoted field v v 1 1 " # unescaped quote must mean end of quoted field \n # if this is really in the data (not just the way you pasted into +the post) # then this may be the error right here -- it should be a comma 2 # and if the line-break wasn't the error, then this is 5 1
The point is that either the quote after vv11 must be escaped or removed, or else there must be a comma after it.

I still don't understand how the presence/absence of or next in the logic has anything to do with whether this error gets detected. Good luck with that.
