Fuji GFX100s shooting from live view freezing software

Needing help with using Fuji GFX100s in Smartshooter 5.

SS connects to camera fine. The live view works, everything looks ok. But then when click shoot, the live view goes blank and disconnects and doesn’t shoot. The Live View does not go back on if clicking enable. It’s like it freezes SS, and I have to close and restart.

Have been using Smartshooter regularly with Canon cameras, this is the first time using the Fuji with it. Found a similar thread, but relates to Lightroom, which I don’t use.

I have checked through all camera settings. Is there some setting in SS or the camera that I have missed?

Thanks
