How do I determine the cause of an "Unknown instruction error"?

I don't know why i cannot move my grass token from Phantom to ByBit wallet, when i do it show me this problem:

Program Error: "Instruction #4 Failed - Unknown instruction error"

It is not about fee( Maybe the token has problem or Phantom has problem idk). My transaction: https://solscan.io/tx/RNkzXiaXyZn6jozq8R22WwK6qWwAT6kY9GBVgTP2TRo4GtpySeYAhr89GBigkxMQeYeu9wjDZBpDHxaPxn8gses
