MacScripter's "Open in Script Editor" buttons

I’ve noticed that MacScripter’s “Open in Script Editor” buttons aren’t working on my M3 MBP since the update to macOS 27.0.1. Script Editor opens, but not with the script texts. Similar buttons on the LNS fora for opening scripts in Script Debugger do still work and the MacScripter ones still work on my older machine.

Is anyone else seeing this? I read yesterday that a potential exploit has been identified involving the “applescript://” URL protocol. It would be handy to get an idea of whether Apple’s now disabled this as a security measure or whether it’s simply a fault on my computer!
