I need Full Stack Blockchain Dev

Description

I developed a dApp game and Smart Contract with Solidity, Next.js and Web3 about 4 years ago. Recently, I tried to run the project again to integrate it into a betting platform - but ran into Front-end.I attempted to fix the errors myself, but I’m not an expert in Node.js or full stack development, so I wasn't successful. Now I'm looking for a senior full stack developer to help me bring this project back to life.The more I try to fix things, the more errors I run into - and honestly, I don't fully understand what's going wrong. I could really use your help. I believe this will be a relatively easy task for an experienced developer.This could also turn into a long-term opportunity. I'm looking forward to working with a skilled and thoughtful developer who can make things clear and work efficiently.
In recent years, AI has developed rapidly. Sometimes people mistakenly believe that AI is superior to humans. However, we need creative developers.*Sorry, don't want to work with AI bot. When making proposal, please add at least two screenshots showing the my web app error(like my attached screenshot) with your computer's current time visible in each.*
