I think that to have NamedTemporaryFile actually remove the file, you need __exit__ to be called. So the usage should be:
with NamedTemporaryFile(...) as test_script:

I wrote a simple test to check it and it gets closed everytime, even with "sys.exit(1) between these lines:
tf = tempfile.NamedTemporaryFile(dir="/home/kitter/Documents/june-gprof/my-gprof-fork/gprofiler", suffix=".tester")
with open(tf.name, "w") as f:
f.write("my-tester")
print(Path(tf.name).read_text())
time.sleep(5)
but I changed it accordingly anyway :)

This creates a problematic flow:
perf_data = temporary file- Exception is raised during
perf script finallyruns and tries to unlinkperf_datawhich is already unlinked.
I suggest you use a 3rd variable (like perf_script_input), then set it to either perf_data OR inject_data, and only unlink perf_data as inject_data is automatically removed.
