    I have to use 4.23 to explore oculus quest dev due too their firmware update. It works but, I'm getting a crash in 4.23 preview 5.

    Repro:
    -Create a project - Blank, scalable 2D or 3D, No starter content, Mobile Tablet
    - When it loads click the settings icon above the viewport, find 'Preview Rendering Level' and change it to anything but Shader Model 5.
    - Engine will crash to desktop and produce this error message:
    Code:
    Assertion failed: bPrimitiveDataInGPUScene || Elements[ElementIndex].PrimitiveUniformBuffer || Elements[ElementIndex].PrimitiveUniformBufferResource [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/SceneManagement.cpp] [Line: 1104] FMeshBatch was not properly setup. The primitive uniform buffer must be specified.

        What about this issue https://answers.unrealengine.com/que...iphone-xs.html ? Will this be fixed ? We had this problem and need to build custom engine to resolve it, I believe you need to check allocators functionality for new iOS devices.
        Seems nobody cares about crashes on new iOS devices... sad Maybe somebody from epic support will comment this issue ?

          Will downgrading Unreal Engine 4.23 to Unreal Engine 4.0 solve my problem? It didn't help however I'll try to wait patiently as best as I can.

            Could you quickly provide your hardware and OS specs? I got several different machines I can compare and see which closest to yours and try to find a clue.

Uninstalling 4.23 beta and reinstalling doesn't show the option either.

              Tried on the latest versions of both macOS Mojave and Catalina.
              our iOS binaries re-appeared this morning, try giving it a shot again if you haven't already

                Did I mention it before already? I have graphics card Nvidia GeForce GTX 1050 Ti and processor AMD Ryzen 5 2600 Six-Core Processor 3.40 GHz, 8 gb ram. Windows 8.1 64-bit(original box version).

                  I wanna updoot this one. I have been crashing when trying to preview mobile renderer as well. Also, it seems like the render target regression is back. My RT works fine in the editor but as soon as I launch to the device it's not there.

                    Yeah, sorry, somehow I got confused by the name and couldn't relate it to a previous post. Well, the specs are really OK. What is possibly missing is the components for Visual Studio, so could you execute the installer and post a print screen from the selected options to install with it. There are a couple of modules that are necessary to install, so I can pin-point what is missing with this screenshot.

                          Yay! Thanks Epic <3

                          Fingers crossed that this fixes some of the Quest / Android badness that's been going down in the last few patches.

                            UnexpectedSquirt It does. Just be sure to specify Quest in the new Project Settings: 'Package for Oculus Mobile devices' array

                              Is there an expected date on full release of 4.23?

                                Yes, but we don't announce specific dates in case that slips.

                                However, it will be soon.
