Hey HeavenlyGamesBoss-
Can you provide the reproduction steps that cause this in a new project? You mention adding a widget as well as source code - does the issue occur with only a new widget added to the viewport or is a custom User Widget class necessary for the crash to occur? If code is necessary, can you provide the code you added to your class? Does the crash occur with an empty widget and, if not, what did you add to the widget itself? Additionally, please provide the callstack from the crash for additional information.
