You've left one of the plugins enabled there.
Does it still crash if you disable all plugins?
Especially given what you say here, I think you are asking for support from the wrong people and need to talk to Adobe, or switch to another PDF viewer, or investigate solutions to Adobe Reader's preview handler crashing in general, as the problem doesn't sound like it's related to Opus:
The only thing I can suggest other than changing PDF viewers is to try to installing Adobe Reader, reboot, then reinstall it.
