@karthiknadig @karrtikr I could today narrow this issue down further. It happens when I have any of the following options set: “editor.formatOnSaveMode”: “modifications”, “editor.formatOnSaveMode”: “modificationsIfAvailable”,

If I am formatting the whole file, formatting works fine.

Also note that I ran the Bisect Extension command and it pointed to the python extension as the source of the issue.

We do not support editor.formatOnSaveMode currently, so closing this issue in favor of https://github.com/microsoft/vscode-python/issues/14323. Feel free to upvote that to raise priority.
