I did `conda update --all today` and now `hvplot` seems broken. Anybody recognize this problem?

It seems to be the same issue as [some widgets like CrossSelector and MultiSelect broken in 1.4.3 · Issue #6865 · holoviz/panel · GitHub](https://github.com/holoviz/panel/issues/6865)

Just updated everything to the same versions as you and updated conda. I have no issues, but I also don’t have `jupyter-panel-proxy` installed. My understanding is the proxy server is only launched when you try to visit the corresponding endpoint, but is it possible there are some other interactions?

I tried removing `jupyter-panel-proxy` but still have same problem.

It’s not clear to me from that issue what packages I should try downgrading. Do you know?

Try downgrading Panel to 1.4.2.

I tried downgrading panel to 1.4.2, but didn’t work.  
And I’m confused: I’m only using hvplot – why is panel even involved?

Aha! Downgrading to `pyviz_comms==2.3.2` fixed the problem for me. Thanks @ahuang11 !

Panel handles the communication between Python and Jupyter. Also what makes the widgets.

Ah, okay! While we are at it, what does pyviz\_comms do? That sounds like communication also!

Hmm, testing Jupyter lab and downgrading pyviz\_comms doesn’t seem to work for me.

After testing a lot of package variations, pinning `pip install panel!=1.4.3` works.
