npm run dev error after upgrading to Spark 4.0

I upgrade my project from Spark 3 to 4 this morning. When running npm run dev I get the following error without much information on the cause at 95%. I’ve attached my npm-debug.log and webpack.mix.js files.

I’m running Homestead on Windows 10. I have symlinks enabled and npm install worked without any errors.

vagrant@homestead:~/amp$ npm run dev

I also facing the same issue. This is what I did to solve the issue:

1. Remove all the Elixir dependencies.
2. Remove less-loader dependency.
3. Clear everything inside the node-modules folder.
4. Do a fresh install for all the node modules. (npm install).
5. Compile the the project. (npm run dev).

Another solution that worked for me:

Make sure you don’t have any other ‘npm run dev’ running for any other projects that you may have opened. In my case, I had another project running, and I installed a new project and then tried to run ‘npm run dev’, this caused the error. Close the first server and try to run the new project and it should work.
