Why I keep receiving this message: "For deep learning, the simulation target language must be set to C++"?

I am using MATLAB R2021b (the latest version). This error also occured in the previous version.
I replaced the "RL Agent" block with a "MATLAB Function" block containing the policy generated for my controller.
I keep receiving this message even after I changed the taget language from "C" to 'C++".
For deep learning, the simulation target language must be set to C++. Function 'MATLAB Function' (#66.286.341), line 13, column 11: "coder.loadDeepLearningNetwork('agentData.mat','policy')" Launch diagnostic report.
Component:MATLAB Function | Category:Coder error
Persistent variable 'policy' must be assigned before it is used. The only exception is a check using 'isempty(policy)' that can be performed prior to assignment. Function 'MATLAB Function' (#66.398.404), line 16, column 19: "policy" Launch diagnostic report.
Component:MATLAB Function | Category:Coder error
Function call failed. Function 'MATLAB Function' (#66.140.167), line 7, column 11: "localEvaluate(observation1)" Launch diagnostic report.

This is the code inside the "MATLAB Function" blcok (which I generated it using the function "generatePolicyFunction"):
function action1 = evaluatePolicy(observation1)
%#codegen

action1 = localEvaluate(observation1);
end
%% Local Functions
function action1 = localEvaluate(observation1)
persistent policy
if isempty(policy)
policy = coder.loadDeepLearningNetwork('agentData.mat','policy');
end
observation1 = observation1(:)';
action1 = predict(policy, observation1);
end

The original poster was trying to use LCC-win64 2.4.1 as the compiler, but R2021b supports only MinGW 6.3, VS 2019, and VS 2017 for those purposes.
