Sleep display seems to have stopped working

The trigger action, sleep display, does not work. The keyboard shortcut, Option, Command, Eject, still works.

Device information:

  • Type of Mac: Mini M1
  • macOS version: 11.0.1
  • BetterTouchTool version: (please post the exact version - not just "the latest one") : 3.510 (1648)

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):

I have found a workaround for this, using the trigger to Execute Shell Script/Task, and entering the command:
pmset displaysleepnow
