Dorico Keeps Crashing When Trying to Delete Instrument

Every time I try to delete an instrument from an orchestral score in Dorico 5, the app crashes (Windows 11, running latest version of Dorico).

Here’s a link to the diagnostic file since it was too large to upload.

It just keeps crashing now every couple of minutes to the point of being unusable. Any help would be appreciated.

Sorry, I can’t help in this case, because it’s on Dorico-side, but I notified Daniel about it, so hopefully he will step in soon.

Thanks for providing your diagnostics. I’ve had a look at the crash dumps contained within, and there seem to be at least two problems: one seems to be caused by Dorico updating its playback data, and crashing when looking up information about a switch in one of the expression maps in use; and the other appears to be related, as you suggest, to deleting a player from the project.

Could you please attach the project itself here, or if it’s too large to attach, email it to me at d dot spreadbury at steinberg dot de, with details of which player or players you’re trying to remove?

Thank you both. Daniel, the project is a little over 5mb, so I will email it to you now.
