Adding instrument causes crash

When trying to add an instrument to this project, Dorico crashes every time. I tried it about a half-dozen times to confirm.

Project is attached. Diagnostics file was too big to attach, so it’s here: https://www.dropbox.com/s/kjmgpi9jsf4cyh2/Dorico%20Diagnostics.zip?dl=0

Thanks,

It crashed for me also. I then noticed you have both a HSO and a Noteperformer Instrument in the Play mode. If you reset the template to use HSO or Noteperformer, then you can add an instrument without crashing.

That did it, thanks!

The good news is that this doesn’t crash in our current development version, so this must be a crash we fixed after shipping 2.1.10.

Thanks Paul, looking forward to it!
