Can this issue maybe get pinned since it's a going to keep happening on any OS using Qt 6.3.1 until this is fixed

#17230 (comment)

It's this same issue

#17230

Seems like a critical issue judging from the ticket filed at Qt. qBt might have to remove the corrupted configs.

Some updates, for those not following it

In case someone else is still having this issue try the following:

1. Uninstall qBittorrent
2. Delete the ~/.config/qBittorrent folder
3. Re-install qBittorrent

It's suggested that Qt 6.2.4, Qt 6.3.2 & Qt 6.4.0 all have the fix/workaround for this issue but only Qt 6.4.0 officially references it (QTBUG-104425 Crash when loading header state in QBittorent) in it's Changelog

This is fixed by https://codereview.qt-project.org/c/qt/qtbase/+/425133 right?

Yes, if QBittorent works in a 6.4, 6.3.2 or 6.2.4 environment.

We should probably make Qt 6.2.4 our minimum supported Qt 6 version.
