gpu coder get wrong results in multiple functions with coder.varsize

The following code is an example, when I use gpu coder to compile to mex file, the result is only output = 0, rather than a required vector array, I do not know how to modify and find other related samples.
function output=main_test(input)
%#codegen
% Map computation to GPU.
coder.gpu.kernelfun;
output=0;
coder.varsize('output');
output = varfun(input, output);
end
function out_var = varfun(in_var, out_var)
for i=1:10
out_var = [out_var, in_var +2];
end
end

Hi Chao, I use my friend's matlab software, the version is R2021b, the Operating system is Windows 10, the GPU device is NVIDIA Quadro k2200.
when I upgraded the matlab version to r2022b update3, the results is right.
Thanks!
