To add another data point: I get no issues (within 25 000 000 iterations) on Windows 11, Python 3.10.14, juliacall 0.9.26, Julia 1.11.6.

Considering [this thread](https://discourse.julialang.org/t/plea-for-segfault-assistance-in-pythoncall-jl/130697) and [this post](https://discourse.julialang.org/t/plea-for-segfault-assistance-in-pythoncall-jl/130697/27) in particular, perhaps you could check if downgrading to Python 3.11 or earlier helps?
