When I launch software developed on QT 5 toolkit in ReactOS, he loads CPU on 100% about 10-15 seconds and crashes with error "memory could not be "read"" or hangs the system or causes BSOD with NTOSKRNL.EXE error after debug mode in normal mode. For example I used Qbittorrent 3.3.10 and Qupzilla 2.0.2. Qbittorrent 3.3.10 causes BSOD after debug mode and hangs the system after uninstalling and installing again. Qupzilla 2.0.2 crashes with error. In debug mode Qupzilla shows the same error, Qbittorrent hangs the system.
