Invalid Handle exception 0xC0000008 with 4.2.2

[xavier2k6]

Please provide the following information

qBittorrent version and Operating System

qBittorrent 4.2.2 (Official) - Windows 10 Pro x64 Version 1909 Build 18363.752

10.0.18363

If on linux, libtorrent-rasterbar and Qt version

N/A

What is the problem

Unhandled exception 0xC0000008

What is the expected behavior

Not to have a Unhandled exception 0xC0000008

Steps to reproduce

EDIT: Enable Handle Checking in Application Verifier

Just started up the program & was waiting for it to fully load up for a few minutes.

All torrents were in paused state before opening the program - so no download/uploading/seeding/checking etc.

See partial stacktrace below - boost asio problem?!

It did not crash per se, in fact the same instance of qBittorrent is currently running, have debugdiag attached as always & have added 0xC0000008 to my rules now for hopefully a full stacktrace if it happens again.
