Error creating directory "\\......\rtwgen_tlc

I'm using Matlab 2017b and have MINGW as compiler. I'm running a simulink file in acceleration mode for many scenarios in a simple for loop,save some parameters on the go, and clear the rest.

for i=1:2000
    warning('off','all');
    out_one=sim(in(1,i)); 
    time(:,1)=out_one.angle_difference.time;
    RRA(:,1:10)=out_one.angle_difference.signals.values; 
    [rows,cols,vals]=find(abs(RRA(:,1:10))>=180,1); 
                if rows>1
                    CCT=time(rows,1);          
                    StabilityIndex=0;
                            else
                                StabilityIndex=1;
                                CCT=1;      
                end
    AA.TSAReport(i,1)=StabilityIndex; AA.TSAReport(i,2)=CCT; 
    save('TSA_removedACOPFs_One.mat','AA');
    clear out_one; clear time;clear RRA;clear rows;clear cols;clear vals; clear angle_difference;
end

Before I run the loop though, I also creat an accelerator model of my simulink file.

model= 'name of my model'; 
load_system(model);
set_param(name of my model,'AccelVerboseBuild','off');
accelbuild name of my model;

When I run the loop, after some iterations I get this error:

Error using my code name (line 378)

Error while JIT Accelerating model

Error creating directory "\\directory of my script and simulation files\rtwgen_tlc":

fl:filesystem:AccessDenied

Under configuration parameters>code generation>advance parameters I can see that there are some options regarding tlc but it seems it doesn't help.

Any ideas on how to solve this?

Could you confirm that the error message naming the directory has the directory name ending in t l c period space ?

Does a directory or file rtwgen_tlc exist in your current directory? Is there any permissions issue that might prevent a directory with that name from being created? What happens if you create it ahead of time?

Sorry, doesn't have period or space. Well there's an empty folder under slprj\accel\my model name\rtwgen_tlc, which must have been something that "accelbuild" creates. I'm not sure what it does though.
