Describe the bug

During the regression tests of #1977, I noticed that some runs weirdly does not pass the test. After the third attempt regression test passed successfully.

Please see the attempts https://github.com/su2code/SU2/actions/runs/4480654814/jobs/7883573846 hybrid_regression_AD.py.

Looks weird to me.
