I am trying to build the next Js app production files to deploy it on cPanel, when I execute
npm run dev the app is working just fine but as I start to build a production file with the help of this video(https://youtu.be/1ykSXau838c) and executes npm run build it gives me an error in the terminal as given below:
PS C:UsershpDesktopreactJs-projectNextJstest-app> npm run build
> [email protected] build
> next build
info - Checking validity of types
info - Creating an optimized production build .node:events:368
throw er; // Unhandled 'error' event
^
Error: EPERM: operation not permitted, open 'C:UsershpDesktopreactJs-projectNextJstest-app.nexttrace'
Emitted 'error' event on WriteStream instance at:

errno: -4048,
code: 'EPERM',
syscall: 'open',
path: 'C:\Users\hp\Desktop\reactJs-project\NextJs\test-app\.next\trace'
}
so I just want to know is there any way to solve this problem?

From next-sitemap repo README.md
"Having next-sitemap command & next-sitemap.js file may result in file opening instead of building sitemaps in windows machines.
As a solution to this, it is now possible to use a custom config file instead of next-sitemap.js. Just pass –config .js to build command."
Next-Sitemap README.md – Building Sitemaps
The above worked for me
Posting comment from Koronag as an answer (as it helped me with this error and seems the most likely cause)…
This error is commonly seen when running a build while the dev server is already running.
E.g. in my case, I had a local build running via
npm run devand was trying to commit/push code, which invoked a Git Hook that also runsnpm run dev.For me, it works fine this answer drives me to the resolver.
I run 2 scripts in terminals:
So after killing the development script it looks perfectly fine!
shut down your dev server first fellas
