Angular Ionic Capacitor build prod: TypeError Cannot read property of 'updateClassDeclaration' of undefined

Question

About 15 minutes ago I was not getting this error, but after running npx audit fix --force this error occurs when running npm run build in my Ionic capacitor project:

Module build failed (from ./node_modules/@angular-devkit/build-angular/node_modules/@ngtools/webpack/src/ivy/index.js):
TypeError: Cannot read property 'updateClassDeclaration' of undefined

Welp, no luck with fixing. I reverted back to its original state in a backed-up folder and didn't use the npx audit fix --force commands. Be sure to always backup your important project files!
