Suddenly, my entire build has collapsed and won't build. I reset the project several days ago with a fresh create-react app build, and it was fine for a bit, and then yesterday - similar problem with a different error:

Failed to compile.

TS2322: Type '{ children: Element; xsDown: true; }' is not assignable to type 'IntrinsicAttributes & HiddenProps'.
  Property 'children' does not exist on type 'IntrinsicAttributes & HiddenProps'.

I've already stripped out some libraries I was using in small place that I suspected of causing conflicting types declarations, but, I'm still getting this problem, and at this point, I'm totally stuck.

CodePudding user response：

I beleive this is because you've updated to React 18 (specifically, "@types/react": "^18.0.0",).

This pull request talks about what has changed.

Because the issue stems from Material Ui 4 component, most likely you'll need to do one of the following:

1. upgrade to Mui5
2. downgrade to React 17
3. wait for this PR to be merged, that seems to alliviate the issue that you have.

(Also, <Hidden/> from MUI4 does implement children with children?: React.ReactNode; just like first link mentions)
