Describe the bug
BTT crashes when trying to open the settings using the Old Configuration UI. (Opening up BTT's settings using the default/new configuration UI does not crash the app.)

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):


Device information:

  • Type of Mac: MacBook Pro (16-inch 2019)
  • macOS version: 10.15.2
  • BetterTouchTool version: 3.219 (1396)

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
Nothing I have tried has affected this crash:

  • completely removing (e.g., preferences and Application Support folder) and reinstalling BTT
  • restarting my computer
  • defaults delete com.hegenberg.BetterTouchTool
  • tccutil reset All com.hegenberg.BetterTouchTool

I met the same problem and updating to the latest alpha version solved it on my Mac.

Yes, this should be fixed in the latest alpha! I'll do some testing today and tomorrow and probably release a stable build then.
