After some testing I discovered that using the "Paint Vertices Single Color node" on event tick is what is causing the issue. Using this node with event begin play will not crash. This also will not crash on a shipping build configuration.
To be more specific if vertex color has already been assigned via the node and you try to assign a new color that is when the crash will occur.
Painting vertices crashes development build projects.
