Error in Embedded Code Generation: Unable to Run 'rtwmakecfg' File

I encountered an issue with embedded code generation in MATLAB R2023b. The specific error message is:

Error using coder.internal.runMakeCfgFiles
Due to the error 'Output argument "makeInfo" (and possibly others) not assigned a value in the execution with "rtwmakecfg" function.', the directory
'C:\ProgramFiles\MATLAB\R2023b\toolbox\slrealtime\simulink\blocks' cannot be run with the 'rtwmakecfg' file.

In the code generation settings, I have already selected the 'ert.tlc' configuration.

I appreciate any help or guidance can provide. Thank you in advance for your assistance!

I can't see end of the error message. Do you have Simulink Real-Time blocks in your model? If so, you'll need to use slrealtime.tlc rather than ert.tlc.

I have seen this happen when you chose a library block that belongs to a target different from the one you are using. In my case, my target was an Arduino but I used a library for a real time card
