Thanks for raising this, to better understand the crash would you be willing to add the callstack information to this case?

Thanks,

Yes in certain cases FNodeDebugData::BranchFlow may not have any node chain data to fetch any data from. Your approach will fix the issue. I’ve logged a bug to tackle the heart of the issue.
