getwin/putwin save and restore a representation of a screen to a file.
That file format has changed for ncurses 6.  Their binding is
probably the least robust of the many functions in guile-ncurses.

I'll see what I can do with regards to a fix.

FWIW, this particular failure is constrained to those two functions alone,
and doesn't indicate any other problems.
