Per attached images, Cursor’s command-click on a variable results with Cursor’s pyright enabled, vs with it disabled (more matches). What am I losing by disabling pyright? What settings can I tweak to get the navigation features of ms-python while enabling it?
Problems happen when you attempt to disable the Cursor Python extension and then restart the language server. See below. I sometimes can get the ms-python extension to work, and sometimes not. I can’t seem to find a reliable way to cause ms-python to work, as it did when I posted my original report.
