I have been getting crashes in particular 22 files that seem to have 'bad' complex profiles.
They sometimes crash straight away on opening, or they will crash soon after.
These complex profiles have 'missing' building materials - but that shouldn't really be a problem.
They show in the Attribute Manager dialogue with a line under their name.
Once I delete these complex profiles the files are fine in 22.
Thankfully the files were all version 20 and could be opened and fixed in 20.
Be sure to send in your crash bug reports and preferably follow them up with your local support people.

I have reported this as a bug but other than the problem seems to be with the complex profile, GS and I are no closer to the actual cause.
