I'm presuming this is on the unreal side. but…
has anyone experienced issues using the niagara csv data interface when playing back in VR? The system plays back fine in the viewport. However in VR mode, it'll glitch and jitter, something a kind to changing ids, or missing ids, with instances appearing at the origin.

It is a known bug on the unreal side.
https://issues.unrealengine.com/issue/UE-61777 [issues.unrealengine.com]

Instanced stereo rendering is not supported in Niagara.
Work around, you can disable it through Project Settings>Engine>Rendering>VR>Instanced Stereo.
Fix targeted for 4.24
