Deleting custom condensing, crash, v4

Hi! I’m trying to sort my horns and get correct condensing-groups.
But, I’m actually not able to do so. I get crash after crash. Trying a few methods, different layouts, but no. Can’t get there.
v4

Can you please do Help > Create Diagnostic Report and attach the resulting zip file here so that we can take a look at the crashes you’re experiencing?

Sure, here

Thanks. The logs are interesting: all of them are crashes when Dorico is drawing time signatures, tempo marks, etc. Does this problem affect just one project in particular? If so, can you please attach it here?

One project (but, not tried this on others).
Where to upload?

You can attach it here, provided it’s 4MB in size or smaller. Please provide the steps required to reproduce the crash as well, as best you can tell what they are.

Sorry, it’s a large work that I don’t share in public.
Other option?

You can send it to me in a private message.

Issue fixed with 5.1
Thanks!
