I have come across a bug that causes Dorico to crash that I can reproduce reliably.
- Start a new empty project
- Add any instrument(s)
- Under Layout Options—Brackets and Braces—Ensemble type: select Wind band
- Dorico crashes
Alternatively, swap steps 2 and 3 and Dorico will still crash.
The rest of the options for ensemble type seem to work fine, and its only Wind band that I have noticed crashing.
