py2app fails to build PyQt5 apps anymore

For a long time I have been happily building my App bundles using py2app.
At some point that stopped working. I do not have a record of exactly
when. Last time I saw everything work was Feb 2021.
I have reduced the problem to a simple test program and scripts to
build and run the test code to show the issue.
As a comparison I have py2app and pyinstaller versions of the tests.
The pyinstaller version works and the py2app version fails.
The code is on github here:
https://github.com/barry-scott/scm-workbench/tree/master/Source/Experiments
Run ./build-py2app.sh to build and run the py2app version.
Run ./build-pyinstaller.sh to build and runt he pyinstaller version.
The scripts:
1. build a venv
2. run gui_test.py from the command line
3. build the app using py2app or pyinstaller
4. run the app.
I am using macOS 12.1 on Intel MacBook Pro (15-inch, 2016).
Python 3.10.1 from python.org.
The gui_test.py code logs to ~/gui_test.log at key points.
Here is the source:
----
#!/usr/bin/env python
import sys
import os
log_filename = '%s/gui_test.log' % (os.environ['HOME'],)
sys.stdout = open( log_filename, 'a' )
sys.stderr = sys.stdout
print('---- gui_test.py ----', flush=True)
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QLabel, QGridLayout, QWidget
from PyQt5.QtCore import QSize
class HelloWindow(QMainWindow):
def __init__( self ):
super().__init__()
if sys.maxsize > (2**31):
size_int_t = 64
else:
size_int_t = 32
py_ver = '%d.%d-%d' % (sys.version_info.major, sys.version_info.minor, size_int_t)
self.setMinimumSize( QSize(350, 100) )
self.setWindowTitle( 'GUI test - python %s' % (py_ver,) )
self.setCentralWidget( QLabel( ' GUI test - python %s ' % (py_ver,), self ) )
def main( argv ):
print('QtWidgets.QApplication()', flush=True)
app = QtWidgets.QApplication( argv )
print('HelloWindow()', flush=True)
main_win = HelloWindow()
print('main_win.show()', flush=True)
main_win.show()
print('app.exec_()', flush=True)
rc = app.exec_()
print('rc', rc, flush=True)
return rc
if __name__ == "__main__":
sys.exit( main( sys.argv ) )
----
On a successful run the log shows:
---- gui_test.py ----
QtWidgets.QApplication()
HelloWindow()
main_win.show()
app.exec_()
rc 0
When it fails it shows:
---- gui_test.py ----
QtWidgets.QApplication()
