Crash in niagara editor when the mesh renderer's static mesh array contains empty entries

Hi there,

Thanks for reporting this issue, and for the well put together repro steps and repro project.

This is a known issue, you can find the issue tracker here. This issue was fixed recently in this commit. If you’re using a source build, and depending on the severity of this issue in your workflow, you may want to cherry pick the commit. Otherwise, this is targeted to be merged back in for the 5.6.1 release.

Thanks,

Hayden
