Safe to downgrade to: a release before 19.0.0

1. Check installed version

npm ls angular

2. UPGRADE to 19.2.23

npm install angular@">=19.2.23"

3. If no update is available yet, DOWNGRADE to a release before 19.0.0

npm view angular versions npm install angular@"<19.0.0"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
