I see the following error in PR #22156 (https://github.com/spyder-ide…

Warning: 0 15:50:35,969 [WARNING] [traitlets] -> Kernel Provisioning: The 'local-provisioner' is not found.  This is likely due to the presence of multiple jupyter_client distributions and a previous distribution is being used as the source for entrypoints - which does not include 'local-provisioner'.  That distribution should be removed such that only the version-appropriate distribution remains (version >= 7).  Until then, a 'local-provisioner' entrypoint will be automatically constructed and used.
The candidate distribution locations are: []

I suspect an issue with jupyter_client since the last successful workflow on 5.x branch had 8.6.1 and this failing one has 8.6.2. traitlets is 5.14.3 in both workflows.

Let's see if this works.
