I got Process finished with exit code -1073740791 (0xC0000409) STATUS_STACK_BUFFER_OVERRUN when import trio

I met a problem when I import trio,it shows Process finished with exit code -1073740791 (0xC0000409) . I use 3.12 for python and it was unrelated to IDE. Is there any idea about how it happens ?

What OS (Windows?)? What happens if you python -X dev -c "import trio"? (I'm not sure anything will change, but...)

My working hypothesis is that something is incorrect in your Python installation because to my knowledge trio shouldn't cause that.

Well at least you're getting an access violation rather than an error about the stack here. I think -X dev enables faulthandler, but maybe python -X faulthandler -X dev -c "import trio" gets more information?

What major version of Windows are you using? (Probably irrelevant because if I had to suspect anything (now that it wasn't Python) it would be something you installed or drivers but...)

Thank you for reply! It get same output using python -X faulthandler -X dev -c "import trio" `python -X faulthandler -X dev -c "import trio" Windows fatal exception: access violation

I am now using windows 11.

Alright. Does this happen when you run just python -X dev? (This should drop you into a REPL) Does it happen if you try python -X dev -c "import cffi"?

Edit: maybe check in Windows safe mode too?

[kjdsfbchkadwbcuiwbcfiw]

No, it won’t happen

Did you ever figure this out or did it fix itself?
