Please note that the same version worked the last time I tried it (about a year ago)

• Operating system: Windows 10
• COCO version: 2.6.2
• Browser : chrome
• python: Conda python 3.11.7

The likely cause of the problem is Cython in Python 3.11. Using (downgrading to) Python 3.10 or lower should do the trick.
