Upgrading only @angular/compiler to version 19.2.17 while keeping all other Angular packages at version 8.0.0 will cause severe compatibility issues. Angular packages are designed to work together at the same major version.

All Angular packages should be upgraded together:

• @angular/animations: ~8.0.0
• @angular/common: ~8.0.0
• @angular/core: ~8.0.0
• @angular/forms: ~8.0.0
• @angular/platform-browser: ~8.0.0
• @angular/platform-browser-dynamic: ~8.0.0
• @angular/router: ~8.0.0
• @angular/compiler-cli: ~8.0.0 (in devDependencies)
• @angular/cli: ~8.0.0 (in devDependencies)

Additionally, upgrading from Angular 8 to Angular 19 is a major version jump spanning 11 major versions. This requires a careful incremental upgrade process following the Angular Update Guide, as there are numerous breaking changes between these versions.
