How to Reproduce

myth analyze myContract.sol

-> contract code can be found https://bscscan.com/token/0xadb58e26d623acc31870318e419d86fb36c3d9c3#code

using macbook m1 with OS venture 13.4.1

Expected behavior

Should return SWC codes

Hi, This should be fixed in the develop -> new 0.24.1 version
Although for some reason the constructor is not being run properly

[norhh]

The constructor not being run properly is likely due to IUniswapV2Router02 being an interface over a contract, so solidity compiler lacks any information on the code and directly relies on onchain code which is not possible locally with mythril without connecting to a chain, if you paste the contract over IUniswapV2Router02, it shouldn't revert during construction
