After updating from Angular 19.1.4 to 19.2.2, I get following error when using changeDetection: ChangeDetectionStrategy.OnPush:

changeDetection must be a member of ChangeDetectionStrategy enum from @angular/core
  Value is of type 'ChangeDetectionStrategy$1'.(-991010)

(ChangeDetectionStrategy is imported from @angular/core as this answer suggests.)

I had no errors before upgrading.

Things I tried:

• downgrading to 19.2.1 (same error)
• rm -rf node_modules and npm install (same error)
• change all remaining angular dependencies from 19.0.0 to 19.2.2 (same error)

Visual Studio Code's Angular Language Extension was up-to-date on my computer as of March 12. It turned out to be a bug in the extension, there is a new version released on March 13 that fixes the bug. See accepted answer.

• This is symptom of dependency duplications. Basicaly your node modules has several @angular/core packages. – Matthieu Riegler Commented Mar 12 at 20:33
• I am confused, everything worked with 19.1.4. No other changes than upgrading Angular to 19.2.2 has been made. – Thomas Commented Mar 12 at 20:37
• And when I downgrade to 19.1.4, everything is fine again. – Thomas Commented Mar 12 at 20:39
• Some dependency is probably pulling a different minor version. It's hard to say which one. You might want to analyze the bundle with ng build --stat-json angular.dev/cli/build – Matthieu Riegler Commented Mar 12 at 20:51
• Merci Matthieu. It turned out to be a bug in the Angular Language Extension. They have released a new version this morning. – Thomas Commented Mar 13 at 11:53
