Crashes when VPN connection changes or is disconnected 😞

[EviLFazZ]

qBittorrent & operating system versions

qBittorrent version: v5.0.1 (64-bit)
Libtorrent version: 1.2.19.0
Qt version: 6.7.3
Boost version: 1.86.0
OpenSSL version: 3.4.0
zlib version: 1.3.1
OS version: Windows 11 Version 23H2 10.0.22631 x86_64

What is the problem?

Only since v5 of qBittorrent, if my VPN changes (manually or automatically) or disconnected (manually or by network loss), it crashes, but did not have this issue with previous versions 😕

Steps to reproduce

1️⃣ Change VPN's location, iP, server, etc
2️⃣ Disconnect VPN
3️⃣ Disable any/all connections with the internet
4️⃣ Disable route/hub/switch
5️⃣ Unplug LAN/disable WiFi

Additional context

Also, who decided in v5 to use Windows accent colour as the text background... it is truly awful 🤮

@EviLFazZ First of all, thank you for a well presented ticket! - however, it's a duplicate of #17082 (still haven't been able to determine where the issue lies our code/one of our dependencies)

I would also just like to ask for clarification what VPN you are using & it's version & if you are using any other software with it like wireguard/firewall?

who decided in v5 to use Windows accent colour as the text background

See #21616

You can disable alternating row color.

..."however, it's a duplicate of #17082 (still haven't been able to determine where the issue lies our code/one of our dependencies)"

Thanks @xavier2k6, i did search a few times and did see this post #17082, but it did not seem similar, because as i said, i never had this issue with any previous version of qBittorrent and only started with v5.0, so i thought it best and proactive to post my exact issue, with supporting details 🤓

"...what VPN you are using & it's version & if you are using any other software with it like wireguard/firewall?"

Yes, i strictly use qBittorrent a VPN, with Wireguard enabled within the application and restrict qBittorrent to only connect when my VPN is actively working 🚫

I use PrivadoVPN with 'Wireguard' enabled and 'Kill Switch' enabled (that includes qBittorrent within the list among others) and currently is v3.10.0 🗒️

See #21616

Thanks and @stalkerok's suggestion helped 👍🏾
...although it still would be nice to have "alternating row colours", and choose colour manually 💭
