Unfortunately it is a bit hard to keep LaTeX-3 and unicode-math in sync due to the frequent changes to the former. Therefore you have to update unicode-math as well. In general, we (I?) try to support the combinations - LaTeX-3 and unicode-math both from the TeX Live DVD - or both from TL-net - or both from TL-contrib (AFAIK not relevant ATM) - or both from CTAN - or both from Github/SVN, but not any possible combination. See also https://github.com/wspr/unicode-math/issues/211 (a related problem, this time caused by expl3 being too old instead of too new). In general such issues are caused by the "big bang" release of LaTeX-3 which saw lots of macros renamed or removed. I hope the situation will get better during the next couple months.
