It's one of top crashes of our app under Android according to Google Play Console.
Most of the time it happens under Android 10. Half of Android 10 occurrences are under Android 9 and some bit under Android 8.
And yes, it happens only under Huawei devices (e.g. Huawei Y9 Prime 2019), similar to other crash reports here (e.g. QTBUG-82617).
The stack is typically this:

I am using this code to initialize timer, nothing unusual:
m_timer = new QTimer(this); connect(m_timer, &QTimer::timeout, m_statesSerializer.data(), &AbstractDownloadsModulesStatesSqlSerializer::saveAll); m_timer->start(1*60*1000);
Timer is created and used at the same thread as its parent.
