It's crashing in the parsing step, leading to a hang; this is visible on
stdout, so I guess your runner script hides that?

$ ./run-flent bursts -l 10
Starting Flent 2.1.1+git.6959463f using Python 3.10.10.
Starting bursts test. Expected run time: 10 seconds.
Exception in thread Thread-8 (_handle_results):

Should be fixed in the latest master, please try that.

Also, BTW, not sure what your wrapper script does, but Flent has a
built-in batch run facility which may be helpful for such multi-run
tests...
