HoloLens 2 App is Crashing, before OpenXR Diagnostic Report.

[StarUser123]

Hello Guys,

i encountered a bad problem with the Unity Version switching from 2021.3.6 to 2021.3.27.
Our App works great with the .6 version, but didnt run on .27. After deploying the App on HoloLens 2 the app starts and the four dots are visible like normal. But after view seconds it crashes and closes the app. I know that the app with version .6 starts normal and at the beginning i have to confirm the microphone message. The message also didn`t appear with version .27. I attached the debug log below.

So i am running out of solutions and dont know what the problem is, because the log didnt tell me something more. I have to say that the last few warnings of missing scripts etc. arent the cause of the crash. Because these warnings are also there if i use .6. Some one encountered a similiar problem and know what causes this crash?

I tried different things like downgrading OpenXR or upgrading MRTK, but this didn`t work. The reason why i tried this was that the .27 version upgradet the above mentioned package (OpenXR). Another package which i consider that this causes problems is the upgraded input system.

Thank you in advance.

Ah, also i upgraded it to 2022.3 lts because this is the target version. But the error is there before .27.

The referenced script on this Behaviour (Game Object '<null>') is missing!
A scripted object (probably Microsoft.MixedReality.Toolkit.XRSDK.Oculus.Input.OculusXRSDKDeviceManagerProfile?) has a different serialization layout when loading. (Read 72 bytes but expected 116 bytes)
Did you #ifdef UNITY_EDITOR a section of your serialized properties in any of your scripts?
The referenced script on this Behaviour (Game Object 'Button_OpenPortSettings') is missing!

Hi Markus,

Note our FAQ :

How to do X using HoloLens?
Unity does not implement AR Foundation support for HoloLens. Microsoft owns and maintains their AR Foundation provider plug-in and build tools. For any questions regarding HoloLens other than specifically the UnityEngine or UnityEditor API’s, please refer to the Microsoft Mixed Reality forums: https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality

In this case it looks like you have serialization issues with MRTK and some third-party plugins that fail to load. I recommend that you reach out to Microsoft and the authors of those plugins for further support.

Hello Andy,

Thank you for your Response. The two errors you mentioned also exists in the old version. Dont know if these errors are the reason for the crash then. I will look into these errors. Maybe something changed the way how errors are handled.

Cheers,

I have an update to this problem. I solved it by installing and setting the Buildtools v143. Before i compiled it with the old buildtools 142 and used VS2019. When i upgraded it to 2022 and used the newer Buildtools i succesfully build and started the app on the HoloLens. The problem is now solved.
