I'm facing the same Error / Exception. Everything works perfect including SaveIndex(), but after loading from file every call to Search throws this exception

Interesting. @ErwanL08 and @gebirgslok can you suggest a Pull Request extending the tests with a minimal case that can be used to reproduced the bug? I can try patching it then.

Same issue, works until the save, but while loading the saved file throws an exception in C#.

@Geekyvk5 , @gebirgslok , and @ErwanL08, I've just pushed v2.9.1 which seems to fix the issue. Please let me know if you still encounter it 🤗
