Steps to reproduce:
1. Create a new project
2. Enable VR

    Indeed this is a show stopper and not specific to VR as the OP title implies. I upgraded to 2018.3.2f1 and have this error spamming my console and killing my frame rate.

    How did this get past QA let alone be unresolved for so long? Can we have an ETA on a fix?

    Still facing this issue on 2018.3.2f1 in a VR project with the standard render pipeline. I notice it happens as soon as my character shoots (instantiating the first particle systems in the scene)

    We have multiple different 0x0 access violation errors in particle jobs that started somewhere during 2018.3 _NOT_ VR related. Eg in ParticelGeomWrite->WriteVBOData

    As this is a null buffer two and it started to occured at the same time I hope they are related.

    What's the ETA to having this resolved, this is a real show stopper and we have a deadline. Hopefully it gets resolved quickly.

    We actually hooked into the PlayerLoopSystem and disabled all particle related loops and saw the issue go away.... but we don't have particles. It is a useful high level switch to turn particles off so non-art devs can keep moving.
