qBittorrent 4.4.0beta3 SIGABRT core dumped on each start since today

[slrslr]

qBittorrent & operating system versions

v4.4.0beta3
Linux Manjaro 5.15 kernel
libtorrent-rasterbar [Installed] 1:1.2.15-1 extra
libtorrent [Installed] 0.13.8-2 community
qt packages 5.15.2

What is the problem?

I have updated Linux 5.15.12-1-MANJARO packages today and qBittorrent stopped launching. So i have updated qbt from git (master branch) to have latest code and ran from within command line:

$ qbittorrent

SIGABRT happens also for v4.3.8.10 (qbt-enhanced) and this older version shows a few popups of torrents failed loading before is aborted. v4.3.9 WORKS(does not have this problem - except it turned several torrent payloads into Downloads directory instead of custom directory set in Category path and marked these torrents as erroneous and i had to manually move some of the file it relocated and recheck). Downgrading glibc and libtorrent-rasterbar one version behind does not help.

what i did wrong/good, what to try please? I am amateur user.

qbt4.4.0beta3 started again 3 times in a row (across 2 reboots), i do not know why it failed to start before. I will update this if that happen again.

Seen another SIGABRT, this time after start when i pause a torrent, so maybe a bit different: #16017
