test_pyptima sometimes fails on windows-lates #274
Description
Could @nbelakovski take a look at this? Thank you very much.
test_pyptima sometimes fails on windows-lates. The failure seems to be non-deterministic, as it may disappear after re-running.
See
https://github.com/opt4ai/prima/actions/runs/22234778043/job/64323529500 (attempt 1, failure)
https://github.com/opt4ai/prima/actions/runs/22234778043/job/64347074482 (attempt 2, success)
