Sorry about that. Both unicode-math and lualatex-math contain a fix for the
same amsopn issue; when I added the fix to lualatex-math, I forgot to adapt
unicode-math. I should be able to come up with a fix easily (but with this
combination the warning is not harmful).
The error about \dddot is weirder. Try loading amsmath before unicode-math.
In general I want to allow loading of amsmath after unicode-math, but right
now there still seem to be a few issues.
