V3 will not convert negative scans

I just installed NLP vs 3 and the negative does not convert and none of the sliders have any effect. I am using Lightroom classic 13. I looked back at some previous issues that are similar and reset my Lightroom preferences and re-imported the images but still have the same issue. Please can anyone let me know any other ways around this - spent the better part of the morning trying to sort this out…
As an aside the shortcut CTRL N doesnt work either.

Update to the most recent version of LrC. I reported the same ages ago but finally sorted it seems.

I’m on Lightroom 13 so up to date… are you on the beta perhaps?
