Why am I Error from material ui component imports

I imported several components from and utils from material UI. I sometimes get an error about the import, but every time I refresh the page the error goes away both locally and on code sand box.

And secondly, I am unable to get my theme to work after doing what I seem right.

And thirdly, a theme that got to work on code sandbox didn’t work locally with the same code, file structure. I am trying to reproduce that error

For the theme, please check the App.js file. it doesn’t work at all.
