Hey @RakhulR, thanks for reporting. I'll move your issue to the Spyder-notebook repository, which is where it really belongs.

You'll receive support there from its maintainer.

I tried to reproduce your issue on Linux, but both undo/redo and shift+enter work for me on Linux. I will try to pip install the package on Windows in a few days and hopefully the issue that you report will appear then.

In the mean time, can you please go to the Options menu in the Notebook pane (click on the icon ≡ with three horizontal lines in the upper right corner about the notebook), select Server Info and copy the results here?

Thanks for your response. I pip installed in one of my other system and the same problems are shown there too.

The below is the server information form the pc I reported the issue:

No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect. A _jupyter_server_extension_points function was not found in jupyter_lsp. Instead, a _jupyter_server_extension_paths function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server. A _jupyter_server_extension_points function was not found in nbclassic. Instead, a _jupyter_server_extension_paths function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server. A _jupyter_server_extension_points function was not found in notebook_shim. Instead, a _jupyter_server_extension_paths function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server.

Thanks for the info. I don't understand right away where those errors come from, but there is definitely something wrong. Some messages mention a package nbconvert_reportlab that I am not familiar with. Is this package also installed on the other system that you have which shows the same problems?

in the other system nbconvert_reportlab is not installed: image

The server info from this other system is:

No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect. A _jupyter_server_extension_points function was not found in jupyter_lsp. Instead, a _jupyter_server_extension_paths function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server. A _jupyter_server_extension_points function was not found in nbclassic. Instead, a _jupyter_server_extension_paths function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server. A _jupyter_server_extension_points function was not found in notebook_shim. Instead, a _jupyter_server_extension_paths function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server.

I did not manage to reproduce exactly the symptoms that you are seeing. However, I tried to install the plugin using pip on Windows several times with different versions and all my attempts were buggy, often so badly that they can't really be used. I tried to find the cause but without success. My investigations have been circling around qtwebengine, but there are too many layers and I can't isolate a simple example exhibiting the bug. I am afraid I have given up on this, because we are changing the build and installation process for Spyder 6 (due in a couple of months) which should bypass the problematic pip modules.

In the short term, the only advice I can give you is to install using conda (or mamba), as the qtwebengine package there is more stable in our experience. Sorry that I can't help more.
