Steps to reproduce

1. vue create xx-xx
2. import pinia less eslint prettier，
3. I don't know when HMR failed，however, HMR of my project is invalid and no error has been reported

What is expected?

code updated in real time

What is actually happening?

After I created the project with Vuecli, the HMR function failed. I don't know why, because there is no error

I think it's probably webpack5， I tried to build VUe3 + TS +less with Webpack5. The page can be accessed normally, but HMR is also invalid

After setting the vue.config.js file, the problem is resolved
