Hi @mrb2015 ,

Streamiz use RocksDbSharp as a dependency and probably this library is not signed, that's why the DLL loader doesn't want to load it because it doesn't signed.
Can you open an issue here please ? https://github.com/curiosity-ai/rocksdb-sharp

In parallel, can you try to sign the dll with this kind of tool. ? https://brutaldev.com/post/NET-Assembly-Strong-Name-Signer

Best regards,
