@snehasreec can you see anything being displayed with the other backends?

[peterdays]

UPDATE: For me the problem was using the most recent version of ipywidgets (8.0.2). I followed the steps described here: #3274

[snehasreec]

I cannot see anything with ipyvtklink as well

[banesullivan]

Downgrading to ipywidgets==7.7.1 seems to be fixing the issue for most people and this is indeed a duplicate/similar to #3274 and #3282. We're working to stabilize this!

I still cannot view any output, following are my jupyter labextension list:

I apologize that we were unable to help you resolve this issue. Unfortunately, we do not plan to further support the pythreejs notebook backend and would like to point you to our new trame based backend that will be available in version 0.38
