You also need to install the matched ChAMPdata to use EPICv2. As the instruction here .
Run below code to install the ChAMPdata contains EPICv2 annotation.
git clone https://github.com/YuanTian1991/ChAMPdata.git
R CMD INSTALL ChAMPdata

It is not clear that you can use ChAMP for the EPICv2 arrays. You might consider instead using minfi directly.
