I am facing a new error while trying to run my Angular 13 version project locally. This happened after I installed Node js 16.6 yesterday.

This is the first line of the error:

Error: Module build failed (from ./node_modules/@angular-devkit/build- 
angular/src/babel/webpack-loader.js):
 TypeError: genMapping.encodedMap is not a function

Here is further details of the error dump:

Error: Module build failed (from ./node_modules/@angular-devkit/build- 
angular/src/babel/webpack-loader.js):

Can someone tell me what's wrong or what I need to do to resolve this issue?

The error isn't helpful, but the reason it happens is because a package in your node_modules (@jridgewell/gen-mapping) is missing. which could be for a number of reason like installation errors, symlinking dependencies in certain ways, etc.

To fix the issue, double check that your dependencies are properly installed, and that the particular package is present in node_modules.
