BTT Setapp keeps restarting

After setting up a configuration BTT suddenly started to restart in loop, crashing each time and consuming a crazy amount of RAM. While restarting, some app icons appear on the Touch Bar, but not the ones I set up. I wish I could copy the log from Mac's console, but I cannot paste a .txt file here.

Could you check whether there are any crashlogs in the macOS console app under user reports? (you can also send them to andreas@folivora.ai)

You can kill BTT completely using this terminal command:
killall BetterTouchTool && killall BTTRelaunch

Killing it doesn't really work during this restart loop. The only way to go that I found is to uninstall.

Here are three of seven crash logs from the most recent attempt to launch BTT:

BetterTouchTool Setapp_2019-10-24-131534_MacBook-von-Jakub-2016.crash (95.1 KB)
BetterTouchTool Setapp_2019-10-24-131524-1_MacBook-von-Jakub-2016.crash (99.0 KB)
BetterTouchTool Setapp_2019-10-24-131454-1_MacBook-von-Jakub-2016.crash (99.0 KB)

Ah it seems to be caused by one of the calender widgets.

Do you remember whether you added a custom display format here?

I wonder whether that contained '{icon}', because that seems to be the only way how it would run into that problematic code path

Could you maybe send me the contents of this folder to andreas@folivora.ai?
~/Library/Application Support/BetterTouchTool (the files that have 3.206 in them would be enough)

To open that folder use Finder => Go => Go To Folder
