2.4.0~RC1 hangs on macOS

[list_email at icloud.com]

I downloaded LyX 2.4.0~RC1 just now, copied to /Applications on macOS 12.7.2. The “default” file opened telling me how great LyX is (I already knew). There was a rapidly repeating series of messages in the status bar--something about indexing and then looking for font Minion etc. After a while I clicked on a red circle with a white “x” in it but nothing happened. I started a new file, typed one sentence into it, and it successfully made a PDF. When I tried to close the new file window LyX refused saying it was busy with a background process. Same when I tried to quit normally, Command-Q. After about five minutes I force-quit LyX. Double-clicked to re-launch, got Apple menu item and LyX menu item and then got a hang (pinwheel, system log report). Had to force-quit again. Repeated attempts to re-launch are the same.
