[Khalyutin]

After update OS to 15.4. (and autoupdate Xcode) crash debug process on breakpoint (application not crash). Crash corresponding with mouse action in application (if same action activate from keyboard not crash debug). First breakpoint maybe work. crash on 1, 2 or 3-d of iteration same breakpoint

Same problem, Mac M4. Started after an Xcode upgrade

• lldb-1700.0.9.46
• clang-1700.0.13.3

I was checking some things now and deleted all the existing breakpoints and re-added them and I can now halt on a break point again.
