I had been checking in Keyboard Maestro, BTT, System Settings Keyboard etc, but could not find anything. I just spotted that the “App Shortcuts” section within, Keyboard Shortcuts", within, Keyboard, within System Settings.
That had a shortcut configured for the Hook app for Ctrl-R to execute the Hook menu Rename item. I must have put this in a while ago before you supported a shortcut directly. It seems this seemed to break running your own Ctrl-Shift-R shortcut. Deleting that App Shortcut and your default Ctrl-Shift-R is working.
Hi, sorry to dig out a post after that long time, but I have the same issue. But for me, there is no app shortcut in the system settings that interferes. Which string in the system settings app shortcut did you use to address this I would like to try setting up a different shortcut, but I cannot figure out how to address this.
