I'm getting below error while creating a new Angular application -

npm WARN deprecated [email protected]: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

I tried the solution given in below link but it did not work for me- Error: Please, upgrade your dependencies to the actual version of core-js@3

When I check version of Angular using 'ng --version' command, I see <error> as version for below listed packages -

@angular-devkit/architect    
@angular-devkit/core         
@angular-devkit/schematics   
@schematics/angular          
@schematics/update

Could you please suggest what went wrong and what needs to be done to fix this?

P.S. - The same functionality was working fine a day before. And the already created projects are running fine locally.

Indeed the issue was with cache. npm clean-install worked.
