I quite frequently get the following error message when running code in the research jupyter notebook in algorithm lab:

Error: Canceled future for execute_request message before replies were done
at a.KernelShellFutureHandler.dispose (/home/lean-user/.openvscode-server/extensions/ms-toolsai.jupyter-2022.3.1001111913/out/node_modules/@jupyterlab/services.js:2:32353)

The instance resets after the error message and I have to run all the code again. I have not purchased a research node - may that be the reason? I also experience the script getting stuck at one cell for no obvious reason - it's fixed when I close the project and re-open it.
