Hi, and welcome to the Vercel Community !
Yes, you can rename the _next folder in Next.js, but it's important to note that this folder is automatically generated during the build process and contains important assets for your application. The folder name "_next" is the default, but you can change it using the distDir configuration option in your next.config.js file.
See relevant docs:
https://nextjs.org/docs/app/api-reference/next-config-js/distDir
Let us know how you get on!
Thanks !, Here's another important:
Error: Could not find the module "/vercel/path0/node_modules/@primer/react/lib-esm/index.js#SplitPageLayout#Header" in the React Client Manifest. This is probably a bug in the React Server Components bundler.
