C10, WIN 10, Saurus 1.1 shuts down computer

Does anybody have problems with Tones2’s VST Saurus 1.1 and Cubase 10?

Any project that uses Saurus 1.1 (64bit) in Cubase 10.0.15 causes my computer to immediately shutdown. No crash warning just straight to “the computer is shutting down”. Opening the same project in 9.5 is fine. I’ve reinstalled Saurus but no luck. Doesn’t happen with any other plug-in.

Even if the problem lies with Saurus, how can anything in Cubase cause my computer to go to “Shut down”? I would understand if I got a nasty blue screen but triggering the “Shut down” command seems very strange…
