This is hitting an assert here: https://github.com/qt/qtbase/blob/5.15/src/gui/image/qpixmap.cpp#L76 It doesn't seem to be an issue in Qt, definitely not one introduced by the recently updated Qt 5.15.17 as the code hasn't changed.
using "coredumpctl gdb" (or generally inspecting the coredump with gdb or running qt5ct under gdb) might reveal more of why the assert has been hit ...
