Description of the issue

I'm building in a clean virtualenv with pyinstaller test.py --windowed
I can't launch the .app bundle by double-clicking nor with open ./test.app in Terminal.
It works fine if I run ./test.app/Contents/MacOS/test

Context information (for bug reports)

• Output of pyinstaller --version: 4.0
• Version of Python: 3.7.7
• Platform: macOS 10.14.6
