BUG: Cubase 15 crashes after changing Short Name in Score Editor

Hi, dear Steinberg developers/QA team,

in Cubase 15.0.030 build 287 Apple Silicon (on macOS Tahoe 26.5.2) there is a memory issue (segmentation fault) in the following situation:

  • I am in a score editor (without selecting any events on a track; it seems to be important), and open Instrument settings
  • I change short name (by the way, tabs do not jump between fields in the form)
  • After that Cubase crashes
