[NbConvertApp] WARNING | pattern 'shell.posix' matched no files When Trying to Activate Python Environment

Followed immediately after by:
`[NbConvertApp] WARNING | pattern 'activate' matched no files
[NbConvertApp] WARNING | pattern 'PythonData' matched no files`

When I try to run conda commands, such as `conda update -n root conda`, it's met with a huge dump of information on the configurables of nbconvert and is followed with `[NbConvertApp] CRITICAL | Bad config encountered during initialization:
[NbConvertApp] CRITICAL | Unrecognized flag: '-n'`.
Not entirely sure how to fix this or what could have gone wrong.

Reproduce the `conda update -n root conda` command and capture why it is being handled by NbConvertApp instead of conda. Trace the nbconvert and conda command entry points involved in the environment, then verify that conda commands run without NbConvertApp warnings and accept their flags.
