CodeBuild is not finishing - hung up on npm install

Hi. I use CodeBuild as a part of CodePipeline for a few months. I ran it a couple of times today.

About 30-40 minutes ago I started 2 CodePipeline processes and CodeBuild hung up exactly in the same moment in both of them - after npm install:

[Container] 2021/08/24 10:34:51 Running command npm install

I tried to click "Stop build" button, but it doesn't change much - it got stuck in "Stopping" status now. Currently they are running for 53 minutes. I've never had a problem like this, and also (as mentioned above), both CodeBuilds worked today correctly.

Do you have any other ways to cancel them, than clicking on "Stop build"? Is there a timeout when they cancel automatically?
