Some Cubase projects always crash first time opening, why?

As written in the subject line, everyone once in a while I have a project that will ALWAYS crash Cubase the first time I try to open it - the second time I try it will load and open. Can anyone explain this or tell me what to do? As a longtime Cubase user it just does not make sense to me. All tips very welcome!

Hi,

Could you please attach the crash/dmp file(s)?
