When I use MATLAB. jl to draw, VScode will directly disable my Julia. But I don't know where the problem lies.

using MATLAB
X1=1;Y1=1;Z1=1;
X2=1;Y2=1;Z2=1;
X3=1;Y3=1;Z3=1;
mat"figure;scatter3($X1,$Y1,$Z1, 'b', 'filled');hold on;scatter3($X2,$Y2,$Z2, 'r', 'filled');hold on;scatter3($X3,$Y3,$Z3, 'g', 'filled')"

The VScode error result is shown above, but my MATLAB will pop up a MATLAB command window as shown below. Did I make a mistake? I reinstalled MATLAB and jl, but it still doesn't work
