When opening Aspect, the application immediately (~1 second) quits. “Aspect” is visible in the top menu bar, the Aspect window flashes then disappears and the application quits.
This sounds like this might be the same issue as Crash on startup - macos 15.6.1. Is this an Intel MacBook Pro, or one of the first 13 inch M1 devices?
We are currently taking a little time off, so I didn’t manage to track this down to its root cause, yet. But I expect to have a release with a fix out either on Monday, or on the following Friday (see also Crash on startup - macos 15.6.1 - #4 by Soenke).
