We encountered this error with pytest 8.2.0.
Not sure if latest pytorch TOT fixed this issue.

Looks like a similar problem to #12263, as seen here: https://github.com/pytorch/pytorch/blob/f1d1e3246f3203a4c9641fcda28b0ed66eb8f4d4/torch/testing/_internal/common_distributed.py#L547

The fix in pytorch would be similar to the one shown here for tornado: tornadoweb/tornado#3374
