utils: imp module is removed in Python 3.12 - get is_frozen() from _imp imp has been deprecated for a long time, and has finally been removed in Python 3.12 . The successor importlib is using the same internal _imp module as imp, but doesn't expose it's is_frozen. Using the internal function directly seems like the cleanest solution. Another alternative to imp.is_frozen("__main__") is sys.modules['__main__'].__spec__.origin == 'frozen' but that seems even more internal and fragile.
