Errors after npm audit fix angular 10.0.1

I ran this older 10.0.1 angular project today, and it told me it had a lot of low vulnerabilities and a few high ones. so i ran npm audit fix to fix them. but now when I try to run it, it gives me these errors:

Error: ./src/main.ts  
Module build failed (from ./node_modules/@ngtools/webpack/src/ivy/index.js):
TypeError: angularCompiler.getResourceDependencies(...) is not a function or its return value is not iterable

Any ideas how to fix this? I couldn't really find any relatable problems or solutions online.

Upgrading the Angular CLI from 10 to 11 works for me.

ng update @angular/core @angular/cli
ng update
