      Summary

      LINQ3 projection fails when using a conditional null check followed by Select().FirstOrDefault() on a nested array property. The workaround using the null-coalescing operator (??) or using .First() works correctly.

      Please provide the version of the driver. If applicable, please provide the MongoDB server version and topology (standalone, replica set, or sharded cluster).
