MicroStation crashes when attempting to open _Whats New_.dgn that is delivered with the examples workspace (...\WorkSpace\Projects\Examples\General\dgn).
This issue is already fixed, so next MicroStation official release will have this issue fixed.
Currently, _Whats New_.dgn file has a reference to structural.ifc. If you rename/remove this “structural.ifc” (it is in the same directory as _Whats New_.dgn in the ...\WorkSpace\Projects\Examples\General\dgn directory) – you should be able to open _Whats New_.dgn file.
If you open the file with an older version of MicroStation (08.11.09.357 or older) and turn off the reference display of the structural.ifc and Office Building.dgn (which references structural.ifc) files the file will open without crashing.
