Angular 17 window not defined

Recently after updating my angular cli from 16 to 17 I have been facing performance issues and I had no idea what is SSR and prerendering so I left them enabled. But the root cause was ssr.

• After installing materialize-css I was getting an error M is not defined. Then I imported it from materialize-css.

• Again I was getting an error window is not defined

I disabled SSR in my angular.json

"server": "src/main.server.ts",
            "prerender": true,
            "ssr": {
              "entry": "server.ts"
            }

to

"server": "src/main.server.ts",
              "prerender": false,
              "ssr": false
