Hey @CodelifeLyu, thanks for reporting. Could you restart your computer and try again? Maybe that helps to solve your problem.

Hey @CodelifeLyu, thanks for reporting. Could you restart your computer and try again? Maybe that helps to solve your problem.

Still not working, if there is anything else I can do?

[CodelifeLyu]

Now I fix it. I dont know how but after upgrading my system from windows 10 to windows 11, the error message disappeared and everything just works.

[milindsmart]

I encounter this problem repeatedly on Fedora 39 and 40.

[ccordoba12]

@CodelifeLyu, that's great news! Thanks for letting us know about it.

@milindsmart, could you post the text of error you're seeing? I'm curious to see if it's the exact same error because the one reported by @CodelifeLyu seems to be related to Windows only.

[milindsmart]

Yes I now think I was too quick to comment tying it to this issue - this only happens to me when opening or closing a project. No traceback is present in the issue reporter. In the internal console I found

/usr/lib/python3.12/site-packages/jupyter_client/threaded.py:73: RuntimeWarning: ZMQStream only supports the base zmq.Socket class.

                Use zmq.Socket(shadow=other_socket)
                or `ctx.socket(zmq.DEALER, socket_class=zmq.Socket)`
                to create a base zmq.Socket object,
                no matter what other kind of socket your Context creates.
                
  self.stream = zmqstream.ZMQStream(self.socket, self.ioloop)
/usr/lib/python3.12/site-packages/jupyter_client/threaded.py:73: RuntimeWarning: ZMQStream only supports the base zmq.Socket class.

                Use zmq.Socket(shadow=other_socket)
                or `ctx.socket(zmq.SUB, socket_class=zmq.Socket)`
                to create a base zmq.Socket object,

  self.stream = zmqstream.ZMQStream(self.socket, self.ioloop)
Wayland does not support QWindow::requestActivate()

Should I post a new issue?

[ccordoba12]

As far as I can tell, those are only warnings and shouldn't be a problem for Spyder. Are you facing a specific error due to them?

[milindsmart]

Sorry missed this - things seem to work okay after the issue too, no functionality I can see that's broken.
