As @krassowski pointed out on Gitter, the failure was probably related to the use of ~ here:

pyodide-kernel/packages/pyodide-kernel-extension/package.json

Line 57 in 996ac7c

"@jupyterlab/builder": "~4.0.7",

Which in a way makes sense, because of the overlap check JupyterLab performs (in https://github.com/jupyterlab/jupyterlab/blob/82051a9d0c6dc93677b0b66560aea48d71aaa043/jupyterlab/commands.py#L2252).

Also other extensions using ^ to define their dependency on @jupyterlab/builder are likely not affected.
