Newer versions of qBittorrent crash at least twice a day (on my computer).

qBittorrent & operating system versions

qBittorrent: v4.5.2 (64-bit) Operating system: Windows 10 Enterprise 21H2 10.0.19044 x64 Qt: 5.15.8 libtorrent-rasterbar: 1.2.18.0

What is the problem?

Newer versions of qBittorrent crash at least twice a day (on my computer). The problem happens with 4.3.9, 4.4.5, and 4.5.2 4.1.9 does NOT crash.

I want to use 4.5.2, and here's my crash report:

Do you use some kind of Proxy/VPN?

@arvidn Looks like some boost.asio exception unhandled in libtorrent code.

[persona-joker]

Yes, I use Ivacy VPN when I use qBittorrent.

Possibly relevant too -> https://github.com/qbittorrent/qBittorrent/issues/18255#issuecomment-1475087975 & (FYI/Reminder) -> https://github.com/chriskohlhoff/asio/issues/1061

[persona-joker]

Looks like this is a known issue. I figured out a few things. qBit crashes every time my VPN disconnects. All I have to do is intentionally disconnect my VPN, and qBit 4.5.2 will crash. 4.2.5 doesn't crash. 4.3.0 and 4.3.0.1 both crash. I'm guessing that the following change in 4.3.0 is why 4.3.0 and everything newer crashes: "OTHER: Support for libtorrent 1.1.x is dropped (Chocobo1)"
