Bug report

Screen.Recording.2025-12-11.at.10.10.25.AM.mov

When running the profiler with a non-existent script or module, it silently launches the TUI with empty output instead of erroring early. To reproduce

./python.exe -m profiling.sampling run --live nonexistent_script.py
./python.exe -m profiling.sampling run --live -m nonexistent_module
