Which Stack to use

Hi everyone, I'm working on a full-stack app to create a project for one of my clients. I've already built a social media app using React.js and Firebase storage, but I've run into some limitations with Firebase. For example, I can't search for posts using keywords, which is a bit frustrating. I tried building the backend with Node.js and MySQL, but the server kept crashing, so now I'm looking for a different solution. I'm considering two options: using the MERN stack or trying out Laravel. If I go with Laravel, I'm planning to use React, TypeScript, Next.js, and MongoDB. Do you have any other suggestions or recommendations? I'm new to Laravel, so I'm open to learning more about it and other tools too.
