After upgrading Angular from version 8 to 11, fonts are looking different, they are blurred. Any ideas on what can I do/check to make them look the same as they were before? Any help would be appreciated. When I run the app locally, it looks better than in the deployment environment.

There is a new optimization for fonts - external font definitions are inlined as part of the production build. According to the bug above, it might not work in some cases.
Try disabling the fonts inlining optimization in angular.json - https://angular.io/guide/workspace-config#fonts-optimization-options
