The imp module was removed in python 3.12. Scroll down to:

• Many previously deprecated cleanups in importlib have now been completed:

...

• Support for find_loader() and find_module() APIs have been removed. (Contributed by Barry Warsaw in gh-98040.)

• Replace removed imp functions with importlib functions:

imp	importlib

... imp.find_module() | importlib.util.find_spec() ... imp.load_module() | importlib.import_module()

This should be fixed with the merging of #77
