Dorico 6 constantly chrashes when I try to open a rather large symphonic work that I am working on. All other files I’ve tried open without problems.
Here is the crash report, hoping that someone can assist.

Sorry to hear you’re running into this crash. From examining it, I believe this is a crash that we have seen with a few scores from users related to proofreading and playing techniques, but to be sure, can you either attach the project here, or send it to me by email at d dot spreadbury at steinberg dot de, including a link to this thread, so I can check?

Thanks Daniel.
I’ve sent an email to you with the project in question.

Hi Daniel,

I have the same problem with a file written in Dorico 5 which I can not work on it at all in Dorico 6, since its crashing everytime I open it.
Beside that, I have one more file (also started in Dorico 3.5, completed in Dorico 5 which goes SO slow, that I am sure there is an error somhwere.

I already sent you an e-mail with that file and now with the new one, but maybe I will get your attention by writing here or maybe I have the wrong e-mail.

Thanks a lot.
