Lots of logs "Unable to find internal function" when ARFoundation starts

Hello,

Lately we had to switch our project to IL2CPP and started having a bunch or errors at the start of our ARFoundation scene. This error occurs 70 times at the start and then it doesn't happen anymore.


08-20 20:20:28.488 24602 10567 E Unity : Unable to find internal function `UnityEngine.Animations.TransformStreamHandle::SetLocalTRSInternal_Injected`

We've tried to use a link.xml file which is also not working:


<linker>
<assembly fullname="UnityEngine.CoreModule">
<type fullname="UnityEngine.Jobs.TransformAccessArray" preserve="all" />
</assembly>
<assembly fullname="Unity.Collections" preserve="all" />
<assembly fullname="Unity.Collections.Tests" preserve="all" />
<assembly fullname="Unity.Burst.Tests" preserve="all" />
<assembly fullname="Unity.Transforms" preserve="all" />
<assembly fullname="Unity.Transforms.Hybrid" preserve="all" />
<assembly fullname="Unity.Transforms.Tests" preserve="all" />
<assembly fullname="Unity.Jobs" preserve="all" />

<assembly fullname="Unity.Burst" preserve="all" />
<assembly fullname="UnityEngine.Animations" preserve="all" />
<assembly fullname="Unity.Jobs.LowLevel.Unsafe" preserve="all" />
</linker>


The Unity version we're on is: 2020.3.16f1


Has anyone had a similar issue? Thank you in advance!

 

When I do not understand what is triggering the error but the error is a trigger at a known point:

• I make a copy of the project
• I start taking off code and content
• I make a test to trigger the error
• If the error is not triggered then the content is responsible for the issue
• In this way, I end up with a game object or a component.
• If it is a Unity component I submit a bug report using that clean project and steps

 

Thank you for the response.

Unfortunately that takes too long since we can only trigger this on the device and each build is taking up at least 10 mins. The error is not breaking anything (as far as we can tell), so we don't know if the time invested is justifiable at all.
We just wanted to fix this quickly in case someone else has gone through this.

Regards!

 

Same issue here, including link.xml not solving the issue.
Could you post some case numbers in case you reported a bug already?
