Calibre crashing

[CountZero85]

Helllo

I have a slight problem that i have been trying to figure out for a while

Specs win 11 64 bit ; calibre 9.11, fanficfare 4.59.6

When I try to run fanfic fare against an author on a wellknown adult site I will ofteen crsh hard so normally even calibre-debug -g would not give an output.
Generally I noticed it crashes under fetching metadata part of the download

When i ran it throught the terminal to gather the crash the last part is

Fatal Python error: _PyEval_EvalFrameDefault: Executing a cache.
Python runtime state: initialized

I ran a disk and memory check tthey passed fine,
I also id a reinstall and update of calibre

Any assistance would be appreciated

you have some security software on your system that is detecting the network access and killing calibre. reboot in safe mode and see if it reproduces.
