Sony A6300 SS5 won't connect

I’ve had no issues with SS4 but now, upon starting up SS5 I connect the Sony A6300, the live view is black, grids are there, software says “camera is ready”, but no image on screen in the display? Camera says “Check the connected device”.

Im baffled, I’ve double checked my camera settings, as well as checked the thread on the Sony a7iv about this. Still doesn’t want to work. Im operating on my battery, not connected to power. (done this with SS4 and had no issues). No software is running, no LR, nothing.

Any ideas?
