Crashed when importing a python file in DLL

[vic4key]

Hi everybody,

I'm using pybind11 in DLL to load a python file code but it crashed when calling the py::module::import(...) function, and it stopped here.

My codes run well in an EXE, but in DLL it crashed.
Currently, I really do not know why.
I googled and tried to fix this issue but did not succeed.
Could anyone gimme an idea?

Thanks,
Vic P.
