"ModuleNotFoundError: No module named 'comm'" when running 'python -m ipykernel install'

Python version: 3.10.14
ipykernel version: 6.29.4

Command:
```shell
$ python -m ipykernel install --user --name=my-venv
```

Result:
```shell
Traceback (most recent call last):

```

Expected result:
```shell
Installed kernelspec my-venv in /Users/beise/Library/Application Support/Jupyter/kernels/my-venv
```

Works properly with v 6.29.3.

Reproduce the failure with Python 3.10.14 and ipykernel 6.29.4 using the reported install command, then compare it with 6.29.3. Start at ipykernel/__main__.py, kernelapp.py, and ipkernel.py, and verify completion when the command installs the my-venv kernelspec at the reported Jupyter path.
