Without a reproducible example it is difficult to determine why the
problem may be manifesting itself.  I would note that you are using
the car package and there may be an interaction between having car
loaded and some of the methods in lme4.  However, without a
reproducible example and some information on exactly what versions of
which packages are attached (i.e. the output from sessionInfo()) this
is just speculation.

The problem is subtle and traces back to your calling the new data
frame "new" thereby overriding the function new in the methods
package.   The right hand side of that assignment in the function
Matrix::fac2sparse should be changed to
names(formals(methods::new))[1] and we will make the change in the
next release of the Matrix package.  Until then you can run the script
if you change the name new to newDF
