Inklab Plugin Issues

[skillful_knowledge5FD1]

I have been using the Blkmarket Inklab plugin since it released with no issues what so ever, but now when I press play, it shows "the command select is not available". I cant look into the action/history as it's a plugin, so I'm really quite stuck

What is it expecting?

A layer with a specific name? A colour mode? No layer, only Background? Should there be a selection active? An alpha channel or path?
