Non-deterministic License Manager Error 4402 with latest release of MATLAB with windows-latest or macos-latest

[traversaro]

I have a GitHub Action job that frequently (around 4 times out of 5) on with release: latest on a step that uses matlab-actions/run-command@v1 with error:

  ======BEGIN LICENSE MANAGER ERROR======
  License checkout failed.
  License Manager Error 4402
  Missing root element in response
  
  Troubleshoot this issue by visiting:

  Diagnostic Information:

  License path:  
  Licensing error: 4402,0.
  ======END LICENSE MANAGER ERROR======
  
  exit status 1

other job that use R2022a or R2022b work fine all the time.

The job is https://github.com/robotology/robotology-superbuild/blob/master/.github/workflows/matlab-one-line-install-test.yml , recent job execution:

• recent job ended with a failure: https://github.com/robotology/robotology-superbuild/actions/runs/6346368869

This issue should hopefully be resolved. Can you please give it a try and report back?

Thanks, I opened robotology/robotology-superbuild#1593 to check this . It is supposed to be solved in general or just for v2? No problem in updating to v2, just to understand.
