In the last 2 hours I have reinstalled TL2018 with no change ;-(

getmap.sty unmodified getmapdl.lua unmodified
pdflatex: tokyo + munich +
xelatex : tokyo - munich +
lualatex: tokyo - munich -

getmap.sty unmodified getmapdl.lua modified
pdflatex: tokyo + munich +
xelatex : tokyo - munich +
lualatex: tokyo - munich -

getmap.sty modified getmapdl.lua modified
pdflatex: tokyo + munich +
xelatex : tokyo + munich +
lualatex: tokyo - munich -

Because of the luatex update, there's no change with (un)modified
getmapdl.lua. After modifying getmap.sty, tokyo.png works with xelatex ,
getmap.png works also with the unmodified version.
Nothing works for me with lualatex, it is always the '3f' error.

Using Cygwin's lua:

modified getmapdl.lua:

jk at HP-kleberj ~
$ lua /cygdrive/c/texlive/2018/texmf-dist/scripts/getmap/getmapdl.lua -m
gm -l "渋谷, 東京"-i png -o tokyo
lua: ...ve/c/texlive/2018/texmf-dist/scripts/getmap/getmapdl.lua:13:

unmodified getmapdl.lua:

jk at HP-kleberj ~
$ lua /cygdrive/c/texlive/2018/texmf-dist/scripts/getmap/getmapdl.lua -m
gm -l "渋谷, 東京" -i png -o tokyo
