NullReferenceException Inside Vuforia IL2CPP Codegen on Google Pixel 7

[altkey-KevinLachance]

We are experiencing a strange issue where Sentry reports an internal Vuforia IL2CPP exception, specifically inside Vuforia’s TryGetMouseDownPosition and IInterfaceFuncInvoker pathways.

The AR experience itself works normally on all tested devices — VuMarks track correctly, Ground Plane tracking works, and no visible failure occurs for users.

However, on Google Pixel 7 devices only, Sentry consistently logs the following crash/error originating from Vuforia-generated IL2CPP code, even though the app continues running without gameplay impact.

A screenshot of the stack trace is included below.

Unity | 6000.2.13
Vuforia | 11.4.4
Device | Google Pixel 7
Architecture | ARM64
Scripting Backend | IL2CPP

Reproduction
This is difficult to reproduce manually because the AR features still function.
However:
Build AR project using Unity 6000.2.13 + Vuforia 11.4.4
Run on Google Pixel 7

@altkey-KevinLachance thanks for the report. We will look into this.

@altkey-KevinLachance is the issue reproducible with Unity 6.0?

[altkey-KevinLachance]

yes we use Unity 6000.2.13 with Vuforia 11.4.4

[ptc-emaggio]

yes we use Unity 6000.2.13 with Vuforia 11.4.4

6000.2.13 marketing name is 6.2 . I wanted to know if the issue is reproducible on an earlier release like 6000.0.38f1 (marketing name 6.0)

[altkey-KevinLachance]

We haven’t tried it on 6.0 since 6.2 is the supported version.

[altkey-KevinLachance]

Do you need more infos?

[ptc-emaggio]

No thanks for the detailed report. We will try to reproduce on our side. If this turns into a blocker for you, then you should try to downgrade Unity as we have not seen such an issue with Unity 6.0

[altkey-KevinLachance]

The issue also happen in 6.1

[altkey-KevinLachance]

If needed, we can also downgrade the project to Unity 6.0 and run additional tests to confirm whether the issue still occurs in that version. Just let me know and we’ll provide the results.
