I wonder if this was just an issue of a delay between the npm upload and the artefact becoming available?

[krassowski]

It looks that all artifacts were uploaded (both npm and https://pypi.org/project/jupyterlab/4.2.0a2/) and release check is passing on CI (#16056) so I will go ahead an undraft the GitHub release.

There is a follow-up task of fixing the examples job thoguh: #16057

It could be yes (this happened with previous releases).
