Project won't open any longer+crash dumps

Hi there
On Cubase Elements 10.0.40. a previously healthy project refuses to open. While loading the project, Cubase quits. Earlier versions and backup files do the same, even those which do not contain more than several audio tracks.
In some cases the project opens, I can start playback, but then everything freezes, ugly digital noise sounds and Cubase quits.
Other apps and other projects work fine. Deleting the preferences did not help.
Since the last successful project opening Ableton Live Lite has been installed, but its removal did not help.
OpSys: Windows 10

I attached several crash reports.

Please help!

After a weekend-long trial-and-erroring it turned out the the Spitfire Labs caused the problem. After uninstalling it, it was possible to open the project again. Of course, I have no information why this happened, but I am quite happy that I could save (most of) my project.
