I'm not sure what the appropriate error message should be here, but I don't think it is the above, maybe something like:

"Error: Dimensions of parameters not compatible with multivariate distribution parameters" "Multivariate distributions cannot have more than two dimensions", "Object x has dimensions: {paste(dim(x), collapse = 'x')}"

instead? But it seems that we are just checking if it has exactly 2 dimensions, so I'm not sure if this error message should be more about that, rather than about multivariate-ness?
