Hi! This looks like something you should report to chirp. From glancing at that stack trace, the crash is happening inside the initialization of a SIP generated module, which suggests that this is more likely a bug with chirp / SIP / how that package was built rather than a bug in CPython.

(p.s. I see you’re using 3.14a6t. Make sure that you’re running everything with supported versions of Python and other dependencies. chirp / SIP may not support 3.14 alphas or free-threaded builds).

Agreed, let's get a pure-CPython reproducer.
