Dragging and dropping a system that contains event context to create nested VFX crashes the editor

-

Oct 03, 2025

Steps to reproduce:

Actual results: Crash

Expected results: No crash

Reproducible with versions: 6.4, 6.3, 6.2, 6.0, 6000.0.47f1

Not reproducible with versions:

Can’t test with versions:

Tested on (OS): macOS

Notes:

It is reproducible with any system that contains Event context, so you can simply create a new system from template and replace Spawner with an Event and this would reproduce the issue.
It is possible that we didn't cover this case while testing Direct Link Event feature :(
There's no callstack in Editor.log, or Editor-prev.log
