Truffle v5.9.3 (core: 5.9.3) Node v18.16.0

I try many solutions to fix it but didn't solve it

Answer 1

We encountered similar issue in past. It is because of the new opcode PUSH0 introduced in Solidity version 0.8.20.

By the way Truffle is now discontinued. To ensure smooth and secure development, I highly suggest switching to Hardhat.

Here is how you can configure your hardhat config:

module.exports = {
  solidity: {
    version: "0.8.20",
    settings: {
      evmVersion: "paris"
    }
  }
};

Alternatively you can use Foundry which also good
