It works here in zsh, did you mistype the closing quote? Although that alters my prompt.

My condolences.

Have a look under ~/.local/share/kwin/scripts/ and see if they're in there. If not, see if they were installed globally by checking /usr/share/kwin/scripts/

I suppose I had better post the full steps to getting all your windows transparent and blurred instead of the terse thing I did earlier.

1. Clone and build Better Blur
2. Open System Settings
3. Go to Desktop Effects
4. Disable blur and enable better blur
5. Go to Window Rules
6. Add a new rule and set window class to unimportant
7. Add Active Opacity and choose your opacity level
8. Add inactive Opacity and choose your opacity level
