Jupyterlab opens default environment

Question

Recently it happened that my jupyter lab does not open the environment that it is started in, but the default environment.

It could be that this issue comes from an update of my OS (Manjaro) I did recently. But I have no clue how to fix this.

I have no idea what I should do now.. :\

This is my OS btw:

Ok fixed it, never mind: It turned out that there additionally to the jupyter package a jupyterlab package, that I had only installed in my main python version. After installing jupyterlab for the environment version, I could use it.

Someone remind me if I forget to put this as solved in 2 days
