Hello Hon Lai,
Sorry to hear about your experience with using Storyline 360 in Windows 11.
I'm using Windows 11 myself and I can confirm that I am not experiencing any crashes when I try to use the action fine tuning feature for screen recordings.
Since the behavior appears to be isolated to your local installation, try doing a repair of Storyline 360 to see if this helps. You'll also want to make sure that you are working locally when making changes to your project file. If the issue persists, open a case with our support team here so we can take a closer look at what's happening.
