I am trying to profile the gpu code. At first, I tried the example in gpucoder.profile. But it always gives an error with something of SIL ServerPort as below. My gpu device is NVIDIA GeForce RTX 2060 SUPER. The host system is windows10 64bits. My Matlab version is 2021a. What's wrong with my gpu device? Could anyone give me some suggestions?

At first, build a gpu_fftn function file in the current directory.

function [Y] = gpu_fftn(X)
  coder.gpu.kernelfun();
  Y = fftn(X);
end

Then ran the commands below in Matlab prompts window.

cfg = coder.gpuConfig('exe');
cfg.GpuConfig.MallocMode = 'discrete';
gpucoder.profile('gpu_fftn',{rand(2,4500,4)},'CodegenConfig',cfg, ...
'CodegenArguments','-d profilingdir','Threshold',0.001);

The error came in several minutes.
