The Inspector is lagging for a few seconds when selecting a text layer where SF Pro font is used. I’m running macOS beta but my wife experiencing the same issues with non-beta software (macos 14, Sketch 100 and SF Symbols 5.1).
This seems related to an issue previously reported. The cause of the lag could be caused by a version of the iOS UI library that has internal SF Pro fonts embedded unintendedly. You can quickly check for this by opening your document and selecting a text layer set with SF Pro (or create a new one)
Nxt, open the font weight dropdown and if you see something like in the image below, you have the internal SF Fonts and this is causing the lag:
