Solution 1:

If you have this on your package.json - 

{
  "scripts": {
    "build": "next build"
  }
}

Now change it to -

{
  "scripts": {
    "build": "NODE_OPTIONS=--openssl-legacy-provider next build"
  }
}

Now run "npm run build". Hope build will work. If not work then you can run - 

export NODE_OPTIONS=--openssl-legacy-provider

Solution 2: Just run this command in Your terminal.

node --openssl-legacy-provider ./node_modules/.bin/gatsby build

Solution 3: Modify the webpack.config.cjs

module.exports = {
    output: {
        hashFunction: "xxhash64"
    }
};
