Angular 11 to 12 upgrade Breaks Styling on Test

[ThisThato]

I recently upgrade an angular application from version 11 to 12. It works locally but it breaks the styling on test and it shows the a CSP error.
I attached screenshots of my angular.json and CSP values.
The application also uses angular material

<add name="Content-Security-Policy" value="default-src 'self'; style-src 'self' 'unsafe-inline' 'unsafe-hashes' 'unsafe-eval'; script-src 'self' 'unsafe-inline'; style-src-elem 'self' 'unsafe-inline' 'unsafe-hashes' 'unsafe-eval';/>
