It is normal using local machine, but once submitted to online render(fox renderfarm) or local mini renderfarm though deadline, it can't finish render.

Change to hosek et al mode is okay.

These files should be located here: "C:\Program Files\Chaos\V-Ray\Maya 2024 for x64\maya_vray\bin". Did you by any chance install V-Ray or Maya in an arbitrary location? Maybe something is messed up with your environment variables (or Maya.env). Otherwise, clean reinstall should resolve it.
