Stubgen generation with Debug Python fails with Assertion

[KerstinKeller]

I am using the stubgen.py provided by nanobind to generate pyi files for my nanobind extension module.
However, for the debug build, which I link agains the debug version of Python, the stubgen generation fails with an assertion:

[build]   1>Generating nanobind_core.pyi
[build]   D:\a\2\s\Objects\typeobject.c:7008: type_ready_pre_checks: Assertion "type->tp_call != ((void *)0)" failed
[build]   Enable tracemalloc to get the memory block allocation traceback
[build]   
[build]   object address  : 00000227A7927920
[build]   object refcount : 1
[build]   object type     : 00000227A79B32E0
[build]   object type name: nanobind.nb_meta
[build]   object repr     : Das Sprungziel - VCEnd wurde nicht gefunden.

Assertion that fails:
typeobject.c

Command that triggers the problem from the command line:

python_d D:\SourceCode\github\ecal\thirdparty\nanobind\nanobind\src\stubgen.py -M py.marker -m nanobind_core -o nanobind_core_d.pyi

Nanobind version 2.7.0
Python version 3.12.7
OS Windows

Running stubgen with the Release Python on the Release extension works just fine.
