commit-analyzer: Step analyzeCommits suddenly exits 0 without analyzing commits

As part of our CI/CD-pipelines we use semantic-release to create new tags within a self-hosted GitLab instance on dozens of repositories. This has been working steadily for ~2 years, but has been broken rather inexplicable since yesterday on all of them.
While the pipelines seem to succeed, as an exit code 0 is thrown, the analyzeCommits step completes without actually analysing found commits:

...
[8:42:57 AM] [semantic-release] › ✔  Completed step "verifyConditions" of plugin "@semantic-release/gitlab"
[8:42:57 AM] [semantic-release] › ℹ  Found git tag 1.0.1 associated with version 1.0.1 on branch master
[8:42:57 AM] [semantic-release] › ℹ  Found 4 commits since last release
[8:42:57 AM] [semantic-release] › ℹ  Start step "analyzeCommits" of plugin "@semantic-release/commit-analyzer"
Cleaning up file based variables
Job succeeded

Running with --debug I verified commits are still found with correct content, and as we’re experiencing it on all pipelines I’m starting to think it has something to do with the plugin itself. I tried running previous versions of both node and semantic-release, but without success.

I’m curious if anyone else experiences the same or notices a faulty configuration in YAML’s above. What baffles me the most is that it has been working steadily for a long time.

Configuration

We configured the pipeline and semantic-release as follows:

.gitlab-ci.yml

default:
  interruptible: false
stages:
  - tag

tag:
  image: node:latest
  stage: tag
  before_script:
    - apt-get update && apt-get install -y --no-install-recommends git-core ca-certificates
    - npm install -g semantic-release @semantic-release/changelog @semantic-release/commit-analyzer @semantic-release/gitlab @semantic-release/git @semantic-release/npm @semantic-release/release-notes-generator conventional-changelog conventional-changelog-conventionalcommits 
  script:
    - semantic-release
  when: on_success
  only:
    - master
  except:
    refs:
      - tags
    variables:
      - $CI_COMMIT_TITLE =~ /^RELEASE:.+$/

.releaserc.yaml
