1. Apply this patch: https://codereview.qt-project.org/c/qt-creator/qt-creator/+/351394
2. Load creator project into creator. Ctrl+Shift+F | Scope: Files in File System | Search for: something | Serach engine: Git Grep | Search
3. As soon as you see the "Shutdown now" printout, close creator. It should crash.
The same may potentially happen with SilverSearcher.
