runtime: Test failed at double initialization assert in System.Text.Json.Serialization.Metadata.JsonTypeInfo.InitializePropCache()

That one is unrelated - It’s a double initialization bug in JSON’s property cache cc @layomia:

which is https://github.com/dotnet/runtime/blob/8f8e8f0493144d87ea06676fec367bdbeeb5ad89/src/libraries/System.Text.Json/src/System/Text/Json/Serialization/Metadata/JsonTypeInfo.Cache.cs#L580
