As a work around, I've found you can explicitly set the reserve threads count if you dive into the liverender 'USER_AREA' and use a wrangle to modify your rendersettings prim

Super - thanks for taking a look Rob. Great to hear a more sensible approach to this is on the to-do list.

Your note on the risk is very helpful, not sure we would have spotted that. We'll look at mitigating by copying the file somewhere first.

But, before that I'm still having now luck getting it to work even with your example. I'm running on Windows (11 specifically) here so wonder if that's possibly causing some complication?
I've attached a screen recording of what I see - the 'renderer' is registered and available in the drop down list, but summoning it doesn't pop up the 'selectFile' ui and I get no print output. Something does appear in the gallery, but it's a blank single pixel.
Do let us know if there's any more info that would help or any other tests we can do.

cheers

And if anyone knows of a much more sensible way to load existing images into he RenderGallery to share that too! Feels like we might be missing something - would be super helpful to know if there's a built in way.
