IL2CPP build failures in Unity 6.5+ #
Details
Building for any IL2CPP target fails. The build log reports an IL2CPP error for System.Span in the aliased Yarn.System.Memory assembly, ending in "System.InvalidOperationException: Sequence contains no matching element". The cause is the assembly aliasing we apply to prevent DLL collisions. The aliased System.Memory assembly it brings in breaks IL2CPP. We tracked this down with the community, and a fix has been in testing with them since 21 July 2026. It should roll out soon.
