I have an interface in PyQt5 that crashes when moving a handle too fast (if done slowly, everything is fine), with no error message. My debug capacities reach their limits as the various functions tested separately work, manually and automatically. It may be caused by a memory leak.
Is there a way to debug such an issue?
Thanks in advance!
settings :

Windows 10
python 3.8.6
PyQt 5.12.3
You can probably use any decent IDE (ex: pycharm) to check where you connect your event "handle moved" and see why it crashes.
