npm run start failed with EISDIR: Illegal operation on directory

[BacLuc]

Is your proposal related to a problem?

npm run start (of react-scripts) failed because in a parent directory (in this case the linux home directory) was a directory named package.json.
(with the error EISDIR: illegal operation on a directory).

This bug happens in the package cosmiconfig, which is a transitive dependency of fork-ts-checker-webpack-plugin

Describe the solution you'd like

An update of fork-ts-checker-webpack-plugin to v 7.2.8 in react-dev-tools would fix the issue.

Describe alternatives you've considered

None, updating seems reasonable.

Additional context

The bug is fixed with version 7.0.1 of cosmiconfig (cosmiconfig/cosmiconfig#260).
fork-ts-checker-webpack-plugin already upgraded cosmiconfig (TypeStrong/fork-ts-checker-webpack-plugin#698) and released a version with the fix (TypeStrong/fork-ts-checker-webpack-plugin@6.5.x...v7.2.8).
