How to find out why an application with PyQt5 crashed?

Question

Python

I ran into this problem: if an application using PyQt5 crashes, then nothing is displayed in the shell window about the error that caused it to crash, just a regular Windows window pops up saying that "Python has stopped working." How to get an error message?

Answer 2

you can try through the traceback module.

from traceback import format_exc
from sys import stderr

## момент на котором предположительно может падать

try:
    ...
except:
    print(format_exc(10), file=stderr) # 10 - глубина стека ошибки
