Bug Error building IL2CPP/ARM64 to Android phone, Failed running UnityLinker.exe, Unity.RuntimeSceneSeri

I am getting a weird build error I can't figure out.

If I run on Mondo/Arm7 it builds fine. Running IL2CPP/ARM64 I get this error:

"Failed to resolve assembly: 'Unity.RuntimeSceneSerialization, Version=0.0.0.0..."

I should add:

- I am using the preview package UI Builder
- I am using MARS/AR foundations so I need IL2CPP/ARM64

Full call stack:

Thank you!

 

Not sure. Any suggestions on how to check?

These are the packages I have.



Should I try uninstalling each one to see?

 

So took me a while but uninstalling MARS did the trick. Will try to reinstall tomorrow to see if the problem comes back.

Thank you for the continued help Josh!

 

Thank you! Will do.

 

Hey Josh,

We are now at the stage of our project that we are going to develop the AR components. I installed MARS and same error again.

I submitted a bug report. How do I track the status?

Thank you!

 

Found the issue. The issue was with the MARS companion package. Removing just that solved the issue.

I will try to add that to the bug report as well.

 

wow your an angel its been 3 days of this for me
