Atom Error: A JavaScript error occurred in the main process (Fix?)

When launching Atom I encounter this error:

I’m running the latest stable release of both Windows 10 and Atom

Have you used Atom successfully in the past? This seems like the sort of thing that a reinstall should fix.

I have used Atom without problems for about a year now, but I will try reinstalling

This worked for me:
If you launch Atom by right-clicking and selecting “Open with Atom” this will launch the editor without this error, however you can not install any packages. You would still probably want to do a full reinstall eventually.

Are you still unable to install packages?
3. find atom folder
4.look in which version the error is, in your case 1.35.1
5. delete this folder
