Dorico crashes after opening Noteperformer's midi settings

Hello everyone, this is a new one. Macbook OSX Sequoia, Dorico 5 and both with Noteperformer 5.0.1 and latest (5.1.2). Whenever I open Noteperformer’s mixer up and going back from playback view to any other view, Dorico freezes. Project is 14 bars of 6 voices completely empty. Already reinstalled Dorico as well. Never had such issues before. What can I do? Thank you very much!

Could you please choose in Dorico from the menu Help > Create Diagnostic Report and post the corresponding zip file in a reply here? Hopefully it contains freeze dump files which tell us where Dorico is hanging.
Thanks

Good evening Ulf! Sorry for the very VERY late reply. I’ve had quite busy days and I have worked on my other computer in the meantime. Thank you for your time!

Hi @Andrea0 , thanks for the diagnostics, but it only contains one hang file, which does not tell me much.
Could you please try to reproduce that crash/freeze again and then open /Applications/Utilities/Activity Monitor.app. At the top middle of that window is a round icon with 3 dots inside. Do a right click on that and choose from the pop-up menu Create Spindump, save the output to a text file, zip that one up and attach the zip file to a reply here.
Thanks

Hi Ulf, thank you again for your time. I will update this as soon as I get back on my other computer. Thank you and sorry for taking too long but I get no mail notification from this so I tend to forget..!

No worries, take your time.
