Description

In package gatsby dependency webpack is pinned to specific minor version "~5.98.0".

It was pinned in #39264, so the bug is more to fix whatever caused it to be pinned, i.e. make Gatsby compatible with newer versions of Webpack, and then unpin.

context:
I wanted to upgrade gatsby ^5.13.3 -> ^5.15.0, but already had newer webpack in my dependencies, hence I ran into

The 'compilation' argument must be an instance of Compilation
  TypeError: The 'compilation' argument must be an instance of Compilation

caused by having multiple webpack versions installed.

at least I fixed by creating an override like so

  "overrides": {
    "gatsby": {
      "webpack": "5.101.0"
    }
  }

I suppose another option would be to downgrade webpack.

Use overrides in package.json (Temporary Fix)

If you just want your project to work immediately without modifying Gatsby itself:

  "gatsby": {
    "webpack": "5.101.0"
  }
}

This forces Gatsby to use Webpack 5.101.0.

You avoid the "compilation argument must be an instance of Compilation" error
