Hello,
I write this problem in the forum as I don’t find where to get Dorico support on steinberg website,
and even I log in on steinberg website and go to the support page I don’t get feedback.
If there is an email to send this case please let me know 
So that’s it, each time I try to write a comment in Dorico it crashes.
In Write mode, I can push the Comment logo on the right side,
I get the comments panel open, I select a bar, then Alt-c or the + button
I get a small window opening, write something, then when press OK it crashes.
I use a MacBook Pro 15 early 2019, Macos 10.15.3 with Dorico 3.1
I attached a diagnostic.
Best regards

Thanks for the crash report, which is so far inconclusive. Could you please attach a screenshot of the name and initials you have chosen for comments, on the General page of Preferences?
Thank you Daniel for your reply.
I didn’t put any name on the General page of Preferences.
Aha, that might be the problem! Can you try entering a name and some initials in there, then see whether or not you still encounter the crash?
I put my name and initials on the General page of Preferences and could then add comments without problems!
Thank you very much
Just to say that I’m using Dorico Pro 4.0.31 on a Mac and am experiencing the same issue as this poster from Feb. 2020 – it seems that using “user Name” for comments leads to crashes, so I created a custom name… either that or my comments were inordinately long… 
If you wouldn’t mind doing Help > Create Diagnostic Report and attaching the resulting zip file here, that would be helpful: I can then take a look at the logs and see what might be going wrong.
