Buildkite build hanging since days

Here's hoping this is the correct tracker, and not already known: Checking on current backlog for ongoing builds, I found that one build seems stuck for almost 3 days: https://buildkite.com/lineageos/android/builds/67930

It seems that the involved agent (build1) is not used for other builds, which might be contributing to the increasing build backlog.

Hope this helps (and hope I'm in the right tracker).
