On CLN v26.04rc3, using MacOS M5 Tahoe 26.4, run uv run pytest -vvvv tests/test_closing.py::test_segwit_shutdown_script
The test fail with the following error:

Additional Context
Please note that the failing node is completely random. The BROKEN log shown above happened on lightningd-31, but in other runs, it fails on different nodes (e.g., 7, 8, 10, 14, 17, etc.).
On Linux the same test is passed.
