Hi @Itzsaggy try this,
Modify package.json (Permanent Fix)

Modify your package.json to include the OpenSSL legacy provider:
1️⃣ Open package.json

Find the "scripts" section and update it:

"scripts": {
"start": "set NODE_OPTIONS=--openssl-legacy-provider && ng serve",
"build": "set NODE_OPTIONS=--openssl-legacy-provider && ng build"
}

For Mac/Linux, use:

"scripts": {
"start": "NODE_OPTIONS=--openssl-legacy-provider ng serve",
"build": "NODE_OPTIONS=--openssl-legacy-provider ng build"
}

This error occurs because you are running Node.js version 17 or higher with Webpack, and OpenSSL 3 (used in newer Node versions) has changed its crypto defaults, which disables the older hashing algorithms Webpack relies on. To quickly fix it, you can run your application with the legacy OpenSSL provider enabled by setting NODE_OPTIONS=--openssl-legacy-provider before your start or build command, or by adding this option directly in your package.json scripts. Alternatively, you can downgrade to Node.js version 16 LTS, which does not have this compatibility issue, or upgrade Webpack and related dependencies to their latest versions, as newer releases have addressed OpenSSL 3 compatibility. While using the legacy provider is the fastest solution for getting your project running, updating your tooling or using a compatible Node version is a better long-term fix.
