Error: JIT compiler unavailable after Angular upgrade from 6 to 13 - jit

Question

I upgraded my angular application from v6 to v13.2.0
I was able to get all the dependencies correct and was able to do ng build successfully.
When I run the application, I get the 'JIT compiler unavailable' error.
As per different blogs, I tried to change tsconfig.json and tsconfig.app.json by adding enableIvy: true, still not able to get the error out.
Any other clues?
