      On v8.0 CI Windows hosts, C:\Program Files (x86)\Windows Kits\10\Debuggers\x64\cdb.exe exists as a non-functional stub. _find_debugger() in dumper.py checked directory existence rather than file validity, returning this stub.
       

      subprocess.Popen raises FileNotFoundError → hang analyzer exits 1 → shell_hang_analyzer.js fails with UnsafeExitError: Mongo shell exited with code 4294967293.
