Trying to load an image to use as a reference fails under recent windows Conda builds giving:
Unhandled Base::Exception caught in GUIApplication::notify.
The error message is: Access violation
I was using FreeCAD_0.18.15248_Conda_Py3QT5-WinVS2015_x64 so I downloaded latest FreeCAD_0.18.15316_x64_dev_win, FreeCAD_0.18.15316_x86_dev_win and FreeCAD_0.18.15316_Conda_Py3QT5-WinVS2015_x64 builds and only the Conda one gives that error again. The other two load the image just fine.
The version that the Conda build reports is 0.18.15299 and not 0.18.15316 as the downloaded file which is strange.

edit: So it looks like this might be fixed with Qt 5.12.1 which is used in latest development builds . If you encountered this could you try with FreeCAD_0.19.17477_x64_LP_12.1.2_PY3QT5-WinVS2015.7z build (or any later that 17477) from here https://github.com/FreeCAD/FreeCAD/rele ... g/0.19_pre and report your result?
