Failure during running test

Hello,
I just installed ase on my Mac. After running a test ($ ase test), I got one failure on test_dos.py:

[gw7] darwin – Python 3.9.0 /Library/Frameworks/Python.framework/Versions/3.9/bin/python3.9
worker ‘gw7’ crashed while running ‘test_dos.py::test_dos’

Do you have some suggestions on how to solve it? Thank you in advance
