Fixed in: 19.2.21, 20.3.19, 21.2.9

Safe to downgrade to: a release before 20.0.0

1. Check installed version

npm ls angular

2. UPGRADE to 19.2.21

npm install angular@">=19.2.21"

3. If no update is available yet, DOWNGRADE to a release before 20.0.0

npm view angular versions npm install angular@"<20.0.0"

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.
