In my below MWE, I am trying to use `\`

for two Sparce matrices, but I am having an error. Any way to solve it?

```
using SparseArrays;
using LinearAlgebra;
using .Threads
using BenchmarkTools
using StaticArrays
A = [1 3 3; 6 9 7;-3 3 4]; As = sparse([1 3 3; 6 9 7;-3 3 4]); b = [1,2,3]; bs = sparse([1,2,3]);
E = As \ bs;
