Hey @najafi82, thanks for reporting. This is an issue with pyzmq 25, which was released some hours ago. Please downgrade to pyzmq 24 in the meantime to have Spyder working again.

I submitted a pull request to fix this to Jupyter-client: jupyter/jupyter_client#914.

[ccordoba12]

My pull request was merged and released in Jupyter-client 7.4.9, so you need to update to that version. I'll add this requirement to Spyder-kernels too so other people don't encounter this issue.
