Updating to 4.25.4 has rendered my project basically useless. As soon as a Blueprint/Widget of any kind is opened, the engine crashes with this error:
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000038
I tried debugging the build with Visual Studio and the crash seems to be caused by a ‘read access violation’ in WidgetBlueprint.cpp (line 969) Screenshot
To anyone thinking of updating to 4.25.4 I would hold off if your project is of decent complexity as there seems to be some unknown incompatibilities with certain peoples projects.
