ah, I‘ll upload it to setapp now, should be available soon
Nice, I will keep an eye on it and will report back then. Thanks!
@Andreas_Hegenberg Just got the update via Setapp and I can confirm that the crashes have been fixed. It's nNow working as expected – thank you, Andreas!
I can confirm that, for me at least, the issue is fixed with the latest BTT version 5.066! Woo-hoo! 
Thank you for your help, and for making this amazing software!
