As you can see in following link . I was not able to build contract using latest rust nighly ( rustc 1.70.0-nightly (17c116721 2023-03-29)) toolchain.
ERROR: Loading of original wasm failed
I got the solution from git issues, here - https://github.com/paritytech/cargo-contract/issues/1058
But now when i am trying to deploy the contract on substrate node it is not responding.
