P1: Critical Description
I started to notice such crashes after updating an app to Qt 6.5.2 among our users crash reports.
It doesn't reproduce for me locally so I can't provide a lot of details, sorry.
Unhandled exception thrown: read access violation.
this->_Callee.**qtTexture** was nullptr.
Call stack:
