Thanks for the link, looking at the run logs it shows the runner being configured for 24.04:

Current runner version: '2.328.0'
Runner name: 'ubuntu-22.04-32core_d39d2b765a5e'
Runner group name: 'large-runner-group'
Machine name: 'pkrvm7jw40e0xgp'
Operating System
Runner Image
  Image: ubuntu-24.04
  Version: 20250831.1.0
  Included Software: https://github.com/actions/runner-images/blob/ubuntu24/20250831.1/images/ubuntu/Ubuntu2404-Readme.md
  Image Release: https://github.com/actions/runner-images/releases/tag/ubuntu24%2F20250831.1

Could you open the Runner in the actions settings page and validate that the image configured for the runner ubuntu-22.04-32core_d39d2b765a5e has the Ubuntu 22.04 image configured for it?

The name of the runner is free text and the image a runner uses can be changed. It's possible someone in your org has updated the runner image but failed to update the name.

Ah, so this is an organization setting that is misconfigured. Now I can go bug the organization owners. Thanks!
