Workaround for now is set <JsonSerializerIsReflectionEnabledByDefault>true</JsonSerializerIsReflectionEnabledByDefault>

It looks like as soon as .NET 8 is released, adding net8.0 to the TargetFrameworks would solve this problem. The other workaround might if the app explicitly PackageReference System.Text.Json and force explicitly to use the newer STJ instead of using STJ 6.0.x
