Ignore Windows stderr flush errors

While running SDXL turbo API from web (comfyui workflow api [Windows]) I encountered below error -

Could you provide instructions + workflow for reproducing the error your PR is intended for? If we can reproduce it exactly on our end, this is more likely to get merged! Thanks!
