Can't open the app after updating

[infeo]

What is your Windows version? Cryptomator needs at least Windows 10, version 1803.

1.6.1 not launch

Ok, i see what the problem is. In short: Your Windows 10 is too old. You need to update it in order to use Cryptomator 1.6.x. There is no other workaround for that. I also checked offical Microsoft Support for Windows 10 v1709. If i read the chart correctly, it ended a year ago. So you should really consider to update.
