object 'CRsparse_rowSums' not found

[KerryAM-R]

I cannot seem to use the FindMarker, FindAllMarkers function. No DE were found with my dataset or the pbmc_small

The error I get is
Error in .local(x, na.rm, dims, ...) :
object 'CRsparse_rowSums' not found

> FindAllMarkers(FindMarkers)
Error in UseMethod(generic = "Idents", object = object) : 
  no applicable method for 'Idents' applied to an object of class "function"
