What happened?

Forge Classic Neo branch was working fine up to two day ago. There was an update and now it no longer starts when installed by stability matrix.

I've tried doing a fresh install and the same thing happens.

Console output

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.3.5 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.
