I don't think 'summary' is actually exported by lmerTest (version >= 3.0-0):
library(lmerTest)
fm <- lmer(Informed.liking ~ Gender + Information * Product + (1 | Consumer) +
(1 | Consumer:Product), data=ham)
lmerTest::summary(fm) # gives: Error: 'summary' is not an exported
object from 'namespace:lmerTest'
On the other hand
summary(fm)
works just fine. lmerTest defines the S3 method 'summary' for
'lmerModLmerTest' objects, so if you change sx <-
lmerTest::summary(x) to sx <- summary(x) you should be fine assuming
that x is of class 'lmerModLmerTest'.
For more details see
https://stat.ethz.ch/pipermail/r-sig-mixed-models/2018q1/026596.html
and perhaps
https://github.com/runehaubo/lmerTestR/blob/master/pkg_notes/new_lmerTest.pdf
(which you were also pointed to previously).
Best regards
Rune

This seems to be from an older version of lmerTest.

Have you checked that you are using a recent version of lmerTest with
3.4.4 and 3.5 RC? I think that might explain the diff.
