And it did happen with 6.181?
If you can reproduce it, please enable the detailed logging via this terminal command:
osascript -e 'tell application "BetterTouchTool" to set_user_defaults key "BTTLogitechDebugEnabled" numberValue 3'
Then if the issue happens send the logs from ~/Library/Application Support/BetterTouchTool/Logs to me (andreas@folivora.ai) go to the folder via Finder => Go => Go to Folder, make sure to include the ~)
