I had several error messages for overriding peer dependencies when doing an npm install. After following the steps proposed by the accepted solution to this post. The most essential part being change the ~ versions to ^, remove node_modules and (if it exists) package-lock.json and run npm install again. I have now reduced the error message to the following :
npm ERR! code ERESOLVE

How do I solve this dependency issue? I cannot simply use --force or --legacy-peer-deps because my next step afterwards is moving from Angular 10 to 13. I tried doing the upgrade without fixing this issue and it forces @angular/cdk to remain at 10.x.x
