When I updated my MiKTeX installation (on Windows 7) today, LuaLaTeX went broken. When I try this minimal example it compiles with PdfLatex and XeLaTeX but not LuaLaTeX:
\documentclass[12pt]{article}
\begin{document}
Hello world!
\end{document}
I get this error message:
luaotfload error: "bad argument #3 to 'string.format' (number has no integer representation)" Lua interpreter stack traceback: ...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:155: in function <...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:152> [C]: in function 'string.format' [C]: in function 'xpcall' ...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:170: in upvalue 'basic_logger' ...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:276: in function 'logreport' ...MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-database.lua:532: in upvalue 'load_names' ...MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-database.lua:625: in upvalue 'lookup_filename' ...MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-database.lua:684: in field 'lookup_font_file' ...iKTeX 2.9/tex/luatex/luaotfload/luaotfload-resolvers.lua:77: in function <...iKTeX 2.9/tex/luatex/luaotfload/luaotfload-resolvers.lua:76> (...tail calls...) ...iKTeX 2.9/tex/luatex/luaotfload/luaotfload-resolvers.lua:247: in local 'r' ...KTeX 2.9/tex/luatex/luaotfload/fontloader-2019-02-14.lua:29709: in field 'resolve' ...KTeX 2.9/tex/luatex/luaotfload/fontloader-2019-02-14.lua:29899: in upvalue 'read' .../MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-loaders.lua:135: in function <.../MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-loaders.lua:134> (...tail calls...)
If I understand it correctly, the main error message is about a syntax error in a luaotfload script? And I guess that it tries to print another error message about some missing font or something?
From fontspec throwing error with lualatex - broken? i tried the command
luaotfload-tool --update
which gave me a similar error message:
luaotfload error: "bad argument #3 to 'string.format' (number has no integer rep resentation)" Lua interpreter stack traceback: ...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:155: in func tion <...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:152> [C]: in function 'string.format' [C]: in function 'xpcall' ...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:170: in upva lue 'basic_logger' ...rams/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-log.lua:276: in upva lue 'logreport' ...MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-database.lua:532: in upva lue 'load_names' ...MiKTeX 2.9/tex/luatex/luaotfload/luaotfload-database.lua:3332: in fie ld 'update' ...ograms\MiKTeX 2.9\scripts/luaotfload\luaotfload-tool.lua:806: in loca l 'action' ...ograms\MiKTeX 2.9\scripts/luaotfload\luaotfload-tool.lua:1622: in fun ction <...ograms\MiKTeX 2.9\scripts/luaotfload\luaotfload-tool.lua:1606> (...tail calls...)

A similar problem (fontspec throwing error with lualatex - broken?) was related to a missing lmodern font package. But I cannot find that package in MiKTeX Console. I have installed similar packages (lm, lm-math, variablelm) but that does not help.
I still guess that the problem is related to the Latin Modern font somehow, because in directory C:\Users...\AppData\Local\MiKTeX\2.9\luatex-cache\generic\fonts\otl, where the font cache is, the font listing goes alphabetically and stops at lmsans10-regular.luc.
Any ideas?
Edit:
If I continue the compilation process by hitting Enter, LuaLaTeX gives a new error message, which maybe can spot the actual problem:
Font \TU/lmr/m/n/12=[lmroman12-regular]:+tlig; at 12pt not loadable: metric data not found or bad.
The font file lmroman12-regular.otf does exist, and looks fine when I double-click on it in Windows Explorer.
...ograms\MiKTeX 2.9\scripts. This doesn't sound like a single user installation. If you run a small document with luatex (not lualatex) which contains\directlua{tex.print(lua.version)}\byewhat do get as output?
