I have installed the latest version 3.201 via Setapp, this version quits automatically now and then.
I noticed the release note that "Some specific, advanced macOS configuration options caused the previous Setapp version of BetterTouchTool to regularly quit after 10-15 minutes. This has been fixed."
But I am pretty sure it still haunts me and one of my friends. I have tried reinstalling it including even using CMM to make a "clean install". Nothing helped.
