I am running into below issue when I try configuring SPFX control on Modern Page, this particular control was working fine without any issue up until now.

Something went wrong

If the problem persists, contact the site administrator and give them the information in Technical Details. Technical Details [SPLoaderError.loadComponentError]: ***Failed to load component "11111111-2017-4bc3-9a39-18dfdd167e1b" (DocumentNavigationWebPart).

It is a polyfill issue. Please add the below polyfill in the webpart.js file (link).

import 'core-js/es6/string';
