Dorico Crashes When Renaming Group

Hi Folks,

Dorico keeps crashing in one of my larger documents whenever I click on an instrument>add to group and then rename the group. This does not happen in a blank Dorico session. I was hoping the crash log may illuminate what is causing it.

I am on the latest version of Dorico 5.1.40.2138
Mac Mini Apple M2 Pro
OS Ventura 12.2.1
32GB of RAM

We have seen this before in large projects. Under some hard to reproduce circumstances we can end up with a re-entrancy problem, where a new edit sneaks in before an existing edit has completed, resulting in a crash. To avoid it until such time as we’ve been able to resolve this, try renaming the group by right-clicking and choosing Rename Player Group from the context menu, then using the little dialog that appears.
