VSCode jupyter extension (on Insider) appears to take a long time to get saved after being used for a while. How to mitigate?

In the past 1-2 months or so, I start to observe that jupyter notebooks in VSCode could run normally for a while, and then start to take a very long time to run a cell or get saved. This can be resolved by running "reload window", but notebook would also lose all the states. Has anyone run into similar problems and are there better ways to mitigate? Thank you!

The screen capture below is an example where this status box would display "saving..." for an unusually long time.

Also, I have observed that when I install jupyter extensions on GCP's vertex AI workbench instance (connected via remote ssh), it always seems to cause the instance to fail to start again once it was stopped, with health status reporting unhealthy JupyterLab API.

I have only observed this with VScode Insider. Currently don't yet know if stable release would behave differently. Thank you.
