so today I wanted to create a new Angular project using the command ng new <projectname> and I got this error:

npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: [email protected]
npm ERR! Found: [email protected]
npm ERR! node_modules/jasmine-core
npm ERR!   dev jasmine-core@"~3.6.0" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer jasmine-core@">=3.7.1" from [email protected]
npm ERR! node_modules/karma-jasmine-html-reporter
npm ERR!   dev karma-jasmine-html-reporter@"^1.5.0" from the root project
npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

I literally tried everything, I updated npm, installed Angular cli again, download and installed node again, npm audit, and a lot of other things but nothing happened.

Also as you can see error told me to use the command with --force, I tried but nothing happened, and with --legacy-peer-deps, I get the error as unknown option.

What is bothering me the most is that everything was working completely right last night and I changed nothing at all but suddenly I'm getting this error today.
