You will not find a single piece of gear on the market that doesn't have bugs. Crash issues are rare in our gear only because they are more simple by comparison. When I was writing the Tempest OS I had tons of crash bugs I had to work through because it was ambitious and quite complex, nearly all of which got fixed as the OS matured.

Professional musicians learn to work around things and create systems to deal with inevitable problems. It's just the reality of the game.
