BiocParallel error - could not find symbol 'useNames' in environment of the generic function

I notice that your MatrixGenerics installation is from the devel branch (odd middle number) while all other BioC packages are release branch (even middle number). This may or may not be the cause, but it doesn't help matters.

I vaguely recall that there was some recent-ish work in matrixStats and MatrixGenerics with respect to consistently adding names to the output. The thing with updates to S4 definitions is that they need to be applied at install time, so perhaps try forcibly re-installing MatrixGenerics, sparseMatrixStats and then DelayedMatrixStats.

Thanks, Aaron--I appreciate it.

Forcibly reinstalled those and it resolved the error. All works well now. Thanks again!
