All of failed.

In what way? According to build log you posted, the build succeeded.

[leogitpro]

6134 ERROR: Can not find path @executable_path/../Python3 (needed by /Library/Developer/CommandLineTools/usr/bin/python3)

The nis not build successed.

A successed build the last will print build successful information.
These stop the moving BUNDLE data files to Resource directory line.

The dist directory app can not open it.

6134 ERROR: Can not find path @executable_path/../Python3 (needed by /Library/Developer/CommandLineTools/usr/bin/python3)

That error is non-fatal, though, as the build process goes on.

15676 INFO: Building EXE from EXE-00.toc completed successfully.

The executable was built successfully...

15698 INFO: moving BUNDLE data files to Resource directory

But because you're building in non-windowed mode, you're also getting an .app bundle, whose last build message is always moving BUNDLE data files to Resource directory.

[rokm]

The dist directory app can not open it.

That's not a build issue, then, but a run-time one.

You should first try running the non-app-bundle executable from terminal to see if that works (because if it doesn't, you'll at least get an error message printed in the terminal). If you're still having problems with .app bundle after that, try adding top-level exception handling in your program, and log exception to file to see what's wrong.
