Comment # 1 on bug 1223448 from Benjamin Greiner

Your log complains about a lot of extensions which are not mandatory for the
core package but seem to be required by your custom configuration. It looks
like when you "updated your python setup", you forgot to update/install them,
too.

- Try running jupyter lab --core-mode
- Try to install the missing extensiosn. Note that elyra  isnot in Tumbleweed,
you seem to mix in pip packages.
- Remove the registration of extensions from your local config.

Unless you can reproduce on a pristine Tumbleweed, I would say this is not a
distribution package issue.
