I've seen this a couple of times in the last few days:

My feeling is that it's related to having a document that is mostly LF but then you add some CRLF (for example during a merge conflict or pasting).

Here's a (zipped, to reduce the chance of anything messing with it) copy of the file from the video in the state that triggers it.

handler_execute_command.zip

And as I hit save, I reload VS Code to ensure it still occurs, but it does not. So probably there is some state involved and it's not just the file on disk. It's unclear if the issue is on the server or the client side.
