Hi, thanks for the report. Can confirm. Appears to be the case of memory leak.

In order not not exit on , we probably have to subclass argparse.ArgumentParser and overwrite error, see https://stackoverflow.com/questions/5943249/python-argparse-and-controlling-overriding-the-exit-status-code

Really not sure on this one wrt. High priority (even though technically a crash) tbh

This is definitively not high priority, it's not even a crash in fact... It's just that invoking this script from within Blender itself indeed generates an error in the argument parser, since the required --text argument is missing. As @lichtwerk pointed out, argparse.ArgumentParser will then terminate the current process with an error message.

But this is not really a problem here, this script is absolutely not supposed to be executed from within a running Blender! It is supposed to be called as part of the arguments of blender from a command line, as documented in its top main comment...

Note that removing the required=true part of the definition of the --text argument also prevents the early forced exit of Blender here, could be replaced by a default value maybe for the template?
