[2025.30280] - Inconsistent Crash when Editing Menu Custom Parameter

TouchDesigner sometimes crashes when editing a Menu custom parameter.

Steps that caused the crash:

  • Create a Base COMP
  • Add a Menu custom parameter
  • Delete the entire contents of “menuNames”

I am not always able to reproduce this crash. It happened while working on a project the other day, and I was able to reproduce it twice today (both in 2025.3028 and 2025.30060) but now I’m having trouble making it happen again even while I follow the same steps. I do have a .dmp file and CrashAutoSave.toe, so maybe something can be gleaned from those:
