    |             ^^^^^

We can solve this using :

 function memcpy(uint256 dest, uint256 src, uint256 len) private pure {
        assembly {
            for {
                let i := 0
            } lt(i, len) {
                i := add(i, 32)
            } { 
                mstore(add(dest, i), mload(add(src, i)))
            }
        }
    }

This loop copies 32 bytes at a time until the specified length is reached. Note that this implementation assumes that the length is a multiple of 32.

I don't have to error. Are you using the right compiler version?

[cryptoryda]

Yes the right complier version is being used

Use --evm-version cancun
