Swapping keys causes systematic BTT crashes

Describe the bug

  1. Create a shortcut "C" that triggers "V"
  2. Create a shortcut "V" that triggers "B"

When you start typing these letters anywhere, BTT crashes all the time and restart. Not limited to C and V. Any swap ends up like this.

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


Device information:

  • Type of Mac: MacBook Pro 15" 2018
  • macOS version: Mojave 10.14
  • BetterTouchTool version: BTT v2.652
    I upgraded to alpha version to see if that's the same and it is. So problem is encountered on both stable release and current alpha version.

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
This problem WAS NOT encountered 2 - 3 days ago. It used to work fine. But now BTT systematically crashes.

Swapping C and V might be stooopid. It was just an example. But € needs option key on a French AZERTY keyboard whereas $ is directly accessible (seriously?). So swapping € with another key (symbol ` in my case) makes sense.

Latest version BTT: tried, still NOK

Reboot: tried multiple times, still NOK
