Stubgen hangs forever for some packages

Bug Report

When executing
stubgen --package great_expectations --output ../dist/result/stubs1/bundled/stubs/great_expectations/

The output is:

2024-09-12T13:12:29+0800 - INFO - Great Expectations logging enabled at 20 level by JupyterUX module.
2024-09-12T13:12:29+0800 - INFO - Could not find local file-backed GX project

Generated files under ../dist/result/stubs1/bundled/stubs/great_expectations/great_expectations/

The generation seems to be successful. But:

1. There are some abnormal logs, and seems that they are from inside the package.
2. The process hangs forever after the last line of output. It doesn't exit.

To Reproduce
Install package great-expectations==0.18.17, and then executing
stubgen --package great_expectations

Expected Behavior

Stubgen should exit after finishing stubs generation.

Actual Behavior

It would hang forever.

Your Environment

• Mypy version used: 1.4.1
• Mypy command-line flags: none
• Mypy configuration options from mypy.ini (and other config files): none
• Python version used: python 3.11

Riproduci il blocco con stubgen --package great_expectations usando great-expectations 0.18.17, quindi traccia il comando stubgen dopo la riga segnalata Generated files. Verifica perché il processo rimane attivo dopo la generazione e verifica che il comando termini una volta completata la generazione degli stub, senza lasciare irrisolti i log anomali del pacchetto.
