Since a few months (about May 2024), Safari started crashing on macOS Monterey (and according to several forum posts also Sonoma).
2024 August update: I tried this approach and it seems to work. It seems that you close Safari once yourself without crashing.
According to this forum post,
You will have to remove:
~/Library/Preferences/com.apple.SpeakSelection.plist
I have tried this, but not evaluated it. So use on your own risk.
