manually refresh scripts in inspector

Hi - my unity software is suddenly not refreshing my script variables when I make changes to them in the external editor. Is there any way to manually refresh this?

you can hit ctrl+R or go to Assets>Refresh, this should manually refresh all the assets in your project. if your external editor is set as the default editor though it should work automatically. have you tried closing unity and reopening it?
To change the external script editor go to Edit>Preferences and make sure it is set to whatever one you are using.
