rollup run dev aborts

Question

I'm working in a Svelte project with rollup. After working for a while, when I try to restart de project in production to see the changes and I write 'npm run dev' the terminal returns a huge message of error:

I've already tried to uninstall and install homebrewer, node and rollup. This situation happens right after I had to quit Visual Studio Code because the localhost:5000 wasn't updating the new changes because of this error: ERR_CONNECTION_REFUSED http://localhost:35729/livereload.js?snipver=1

In order to solve that (with no success) I've tried to make changes at rollup.config.js following different advices from the stack overflow issues like, updating the LiveReload plugin for rollup, this potencial solution or this one, among others. None of them has worked for me. Any tips? Thanks!

I'm not sure exactly what the issue is but I've been using a temporary work around by increasing the node heap memory allocation in my local environment. Setting export NODE_OPTIONS=--max-old-space-size=8192 increases the node heap memory allocation to 8GB. Note you may have to change 8192 to some larger multiple of 1024 in order to have sufficient heap memory when building depending on the size of your application.
