It imports OK here, but then doesn't run as I don't have perlscript installed.
The crash dialog in your screenshot shows the Run Script Thread is crashing, so my guess is the script is importing and then being run to generate the new name preview, and the script engine itself is crashing. (Not much else runs on that thread.)
A crash dump should be created which you can send to us to check. That should confirm whether the crash is within Opus or within the script engine.
If it's the perlscript interpreter that is crashing then it would probably only be something the vendor can fix, but it's always possible the crash dump may reveal something else is happening.
