Can not use the "/" shortcut on macOS

[a83313886]

Recently ,I update this software to latest version on my mac.
I found that the shortcut of inserting common type element not works.
Previously , I press the "/" key in the editing view, a drop down list about the element to insert will occur, but now, nothing happen.

Environment

Software Version 2.1.2
System: MacOS Catalina 10.15.7
