After upgrading to Xcode 12.4, the build jobs have stopped working for me. My only clue is that the new version uses parallel builds and the main process is probably replaced by other child processes and therefore the job always fails unexpectedly shortly after it’s started without any error message…

Hah, upgrading the gitlab-runner from 10.8.0 to 13.9.0 solved the issues!
