The output of hunspell -D is:

Which causes the error since none of the listed dictionary files ends in
.aff, which causes the hunspell-default-dict to be nil on line 1179 in
ispell.el, which causes the error in the next sexp. The consequences of
this error are that spell checking does not work with hunspell and it is
not possible to set a dictionary via ispell-change-dictionary.

The quick and dirty fix of changing the line to

(setq hunspell-default-dict (or "british"
                                 hunspell-multi-dict
                                 (car hunspell-default-dict)))

(added "british" to the or) the problem goes away, and spell checking works
as expected.

This is already fixed in the Emacs repository, the fix will appear in
the upcoming Emacs 26.2.

The problem is caused by an incompatible change in Hunspell 1.7.0
regarding the output of "hunspell -D".

Thanks.
