[Python] Import error of a .pyd file (AI, leave me alone please; my title is great)

I have a .pyd that I generate with swig. Today, I upgraded from python 3.7 to 3.11, and it stopped loading.

I renamed my file to foo.pyd. Within the interpreter, I ran import foo. It gives the error

ImportError: DLL load failed while importing foo: The specified module could not be found.


Usually, the problem is a missing dependency (.dll). I checked with dlldiag

and nothing is missing.

Moreover, I used winapi to win32api.LoadLibrary( foo.pyd ) and win32api.GetProcAddress( PyInit_foo ). No problem.

Why doesn't it load? What's up with the useless error message?
