I can confirm that downgrading (mamba install jupyterlab=3.0.0) also fixes this issue for me.

I get “Error displaying widget: model not found” with the following env (and jupyterlab 3.6.1):

$ mamba list jupyterlab
# packages in environment at /Users/jklymak/mambaforge/envs/LP22a:
#
# Name                    Version                   Build  Channel

jupyterlab 3.0.0 works though.

Sorry I didn’t mean to close this issue 😕 maybe 3.0?
