Getting error in RunAzimuth function with "bonemarrowref" reference on Seurat object

[JainRit]

Hi,

I keep getting this error message "Error in .local(x, na.rm, dims, ...) : object 'CRsparse_colSums' not found" when I try to run the RunAzimuth function to create a Seurat object. I am using the bonemarrow reference dataset. Any tips on how I can resolve this error? Thank you!
