Move Right a Space keyboard shortcut stopped working

For years I've happily used the F5 key to move left a space with help from BetterTouchTool, and the F6 key has allowed me to move right a space. In the past few weeks the F6 shortcut stopped working. I enabled alpha builds and restarted and continued to encounter the issue. The F5 shortcut continues to function as expected. I tried enabling and disabling the shortcut, I deleted the F6 shortcut and mapped the key again to the option to move right a space, and I tried creating a new preset in BTT and making the new one the master. So far I've had no luck in finding a workaround. Any guesses on the culprit? Thanks so much for software I have used daily for several years, for work and recreation.

Affected input device:

Keyboard

Device information:

  • Type of Mac: MacBook Air 13-inch M4 2025
  • macOS version: 15.6.1 (24G90)
  • BetterTouchTool version: (please post the exact version - not just "the latest one")

go to System Settings => Keyboard => Keyboard Shortcuts => Mission Control and check whether either of these shortcuts has a warning triangle. If so, please assign a different shortcut.

BTT makes use of these internally.
