Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of Python 3.13.5.

What's new in this version:

Windows:
- Avoid distributing modified pyconfig.h in the traditional installer. Extension module builds must always specify Py_GIL_DISABLED when targeting the free-threaded runtime.

Tests:
- Add test.support.subTests()

Library:
- Do not normalize locale name ‘C.UTF-8’ to ‘en_US.UTF-8’
- Restore support of integer-like objects with __index__() in random.getrandbits()
- Raise a correct exception for values greater than 0x7fffffff for the BINSTRING opcode in the C implementation of pickle
- Backported bugfixes in zipfile.Path from zipp 3.23. Fixed .name, .stem and other basename-based properties on Windows when working with a zipfile on disk
- email: Fix TypeError in email.utils.decode_params() when sorting RFC 2231 continuations that contain an unnumbered section
- email: Fix parsing of email message ID with invalid domain
- Fix libc thread safety issues with os by replacing getlogin with getlogin_r re-entrant version
- Fix formatting issues in json.dump() when both indent and skipkeys are used

Core and Builtins:
- Roll back changes to generator and list comprehensions that went into 3.13.4 to fix gh-127682, but which involved semantic and bytecode changes not appropriate for a bugfix release

C API:
- Fix Py_RETURN_NONE, Py_RETURN_TRUE and Py_RETURN_FALSE macros in the limited C API 3.11 and older: don’t treat Py_None, Py_True and Py_False as immortal
- Implement PyObject_DelAttr() and PyObject_DelAttrString() as macros in the limited C API 3.12 and older
