Please provide the following information

qBittorrent version and Operating System

qBittorrent-nox 4.2.1
Debian 10 amd64

If on linux, libtorrent-rasterbar and Qt version

Qt: | 5.11.3
Libtorrent: | 1.1.11.0

What is the problem

qBittorrent crashes on startup after setting up proxy

What is the expected behavior

No crashes on startup

Steps to reproduce

Configure proxy in web interface (tested with SOCKS5 and HTTP). Proxy is required to be operational (qBittorrent seems to not crash when proxy settings are incorrect)
Save settings. (Connection with proxy seems to work before restart)
Try restarting qbittorrent-nox

Extra info(if any)

Duplicate of #9667. Probably fixed in some later Qt version because i don't see reports with this stacktrace lately.
