BSOD System_Service_Exception before and after total windows reinstall

[ALEX8642]

qBittorrent version and Operating System
qBittorrent v4.3.6 (64-bit)
Qt: 5.15.2
Libtorrent: 1.2.14.0
Boost: 1.76.0
OpenSSL: 1.1.1k
zlib: 1.2.11
Windows 10 Pro build 19043.1081

What is the problem
System_Service_Exception BSOD (sometimes the system completely freezes without BSOD as well). This started out as a weekly crash, then a daily, then every few hours. Totally reinstalled windows, went away for a week, now it has returned again and happens within minutes of booting. Note that my use case is from a power user perspective. I am hosting 604 large (50gb+) torrents on this client. Issue does not happen with qbittorrent is not running.

What is the expected behavior
That it does not crash.

Steps to reproduce
Seemingly random. System runs 24/7 with only occasional restarts for windows updates. After reinstalling windows it went away for about a week, then returned. Now I cannot run the application anymore as it causes a BSOD within minutes. At one time the app itself would simply close without error as well (nothing in logs), but that was before the reinstall.

Note that there are no errors or other noticeable comments in the qbittorrent logs. No difference between an old log without the issue and a new log at the time of the crash:

example below:

...aside from disabling peer discovery this is only other thing I did: I am using custom them - mumble-dark.qbtheme

@ALEX8642 Thank you for the dump, however Please read through https://github.com/qbittorrent/qBittorrent/blob/master/CONTRIBUTING.md and fill in the issue template properly. It is not optional.

We need to know the qBittorrent version etc etc.

Apologies. I tried to update it... Let me know if it needs more info. Hard to get much considering the system just crashes now within minutes of opening the application.

BSOD's are driver or hardware issues most of the time.

[FranciscoPombal]

This is a problem with your hardware or drivers, not qBittorrent. Converting to discussion.
