Control module properly installed with spyder-kernels, but not found in importing

[UrielLeFey]

Description

What steps will reproduce the problem?

I installed 'control' using conda install -c conda-forge control

Then I installed spyder-kernel, using conda install spyder-kernel control -y

It said it installed successfully, but I still get the error message.

Traceback

Hi @UrielLeFey thank you for the feedback! Could it be possible for you to install Spyder using the current user option instead of the all users option? There is an issue related with using custom interpreters and the Windows standalone installer using the for all users installation option due to the space in the path (#16562) so reinstalling but using the current user option could help.

Also, did you set the custom interpreter option pointing to the Python interpreter from the env where you installed the control and spyder-kernels packages, right?

Any new info in order to better understand what could be causing the issue is greatly appreciated. Let us know if the info above helps!
