Error: 'NoneType' object has no attribute 'terminate'

[Heegreis]

When the version of clearml-session is between 0.11.0~0.13.0, I got the error same as the title after starting SSH tunnel.
My OS is Windows 11.

According the release log Release PyPI v0.11.0 · allegroai/clearml-session, I tried to edit the code of clearml-session:

if sys.platform == 'win32':
    import msvcrt  # noqa
    import wexpect_venv as pexpect

to

if sys.platform == 'win32':
    import msvcrt  # noqa
    import wexpect as pexpect

Then it solved the error.

Following is my relatied package version:
wexpect 4.0.0
wexpect-venv 4.0.2

Can confirm this, some users are experiencing this at my org too.

Appears to be caused by this line:

clearml-session/clearml_session/__main__.py

Line 884 in 5b9b09e

child.terminate(force=True)

Suggests to me that pexpect is throwing an exception here as that is the only line that would cause child to be None.
