The exe file generated after the high level synthesis does not work

I would like to simulate only the inference part of a MNIST three-layer fully coupled neural network with high level synthesis and modelsim.
The weights will be input from a txt file.
After the high level synthesis, an exe file is generated, but when I run it, nothing happens. What could be the cause of this?
I ran the file input program (fileinout.cpp) for practice and it worked fine.

The inference program works when I don't use hls.(same program)
