Also some debug Output, not sure whether it is related:
Debug: there is alread a type at 0 (...\MuseScore\libmscore\staff.cpp:955, Ms::StaffType* Ms::Staff::setStaffType(int, const Ms::StaffType*))
Debug: tick2measure 97920 (max 80640) not found (...\MuseScore\libmscore\utils.cpp:60, Ms::Measure* Ms::Score::tick2measure(int) const)

Edit: at least that last message is related, because tick2measure doesn't find tick 97920 , it Returns a nullptr and this gets dereferenced in the next step
