shellcheck hangs and exits after timeout on ubuntu-latest (24.04) but does not on local ubuntu 24.04 install

Describe the bug
shellcheck hangs and exits after timeout on ubuntu-latest (24.04) but does not on local ubuntu 24.04 install.
we use shellcheck to check our bash scripts for any formatting errors at pi-apps. after the automatic update of ubuntu-latest from ubuntu-22.04 to ubuntu-24.04 we noticed that shellcheck hangs and the runner kills the application after a few minutes on ubuntu-24.04 when it did not on ubuntu-22.04. This issue occurs with 100% frequency on the ubuntu-24.04 runners. This issue does NOT occur on a local ubuntu 24.04 install on real hardware so I deemed it an issue with the github actions runner or the hosted cloud hardware configuration.

See the following actions for the error:

To Reproduce
Steps to reproduce the behavior:

1. setup a ubuntu-latest (ubuntu-24.04) action

Runner and Worker's Diagnostic Logs

logs_33252108520.zip

Start with the linked GitHub Actions job log and the attached runner diagnostic logs, then reproduce the command on the specified ubuntu-24.04 runner image using the referenced pi-apps gui file. Compare the hosted runner behavior with local Ubuntu 24.04 execution and trace where shellcheck stops responding. Done means the hang is explained and the runner or execution path no longer times out on this reproduction.
