webpack defineConfig Multiple assets emit different content to the same filename

This issue typically occurs when multiple assets are emitted with different content but have the same filename. It can happen when using webpack's `output.filename` option or when using plugins like `MiniCssExtractPlugin` or `HtmlWebpackPlugin`.

To resolve this issue, you can try the following solutions:

1. Ensure that each asset has a unique filename: Make sure that each asset emitted by webpack has a unique filename. You can use placeholders like `[name]`, `[id]`, or `[contenthash]` to generate unique filenames based on their content or other factors.

2. Use the `output.chunkFilename` option: If you are using code splitting or dynamic imports, you can configure the `output.chunkFilename` option to generate unique filenames for dynamically loaded chunks. For example:

output: {
  // ...
  chunkFilename: '[name].[contenthash].js',
},

3. Check for conflicting plugins or loaders: If you are using plugins or loaders that manipulate the filenames, ensure that they are not conflicting with each other. Some plugins may override the filename configuration set by others, leading to conflicts.

4. Upgrade your webpack version: Sometimes, this issue can be caused by a bug in a specific version of webpack or its plugins. Upgrading to the latest version of webpack and its plugins may help resolve the problem.

If none of these solutions work, please provide more details about your webpack configuration and any relevant plugins or loaders you are using, so I can assist you further.
