Getting crashes on version 2.29.799 now, about a couple of times a day. Haven't had this problem before on Windows 10.
I don't even know the app has crashed until I try to access a file on the BC drive and get an error. The system tray icon is still there until I mouse over it, then it disappears.
Restarting Boxcryptor always fixes it, but it's quite annoying. Seems to be random as it happens whether computer is in use or idle.
