WASM module instantiate failed on Mac

[spino17]

I installed iwasm using the command: brew install wasm-micro-runtime. Then checked iwasm --version which outputted: iwasm 2.0.0. Now I have a main.wasm which I build from a cpp project using wasi-sdk/bin/clang++. When I am trying iwasm main.wasm, it is giving me below error:
